Description

Includes

Each box of E-Gel 48 gels contains 8 gels and a manual.

Invitrogen E-Gel 48 high-throughput precast agarose gels with or without SYBR Safe DNA Gel Stain are designed for fast, convenient, and less-hazardous DNA sample electrophoresis.

Invitrogen E-Gel 48 high-throughput precast agarose gels with or without SYBR Safe DNA Gel Stain are designed for fast, convenient, and less-hazardous DNA sample electrophoresis. Each E-Gel agarose gel cassette contains all components required for efficient gel separation and analysis—just load your samples and run.

Each gel contains 48 sample wells and 4 marker wells in 1%, 2%, or 4% high-resolution agarose with a 3.2-cm run length. The various agarose percentages are used to separate DNA fragments of different sizes:

  • 1% agarose gels: DNA fragments between 400 bp and 10 kb
  • 2% agarose gels: DNA fragments between 50 bp and 3 kb
  • 4% agarose gels: DNA fragments between 10 bp and 500 bp

Each cassette is individually labeled with an EAN39 bar code that is recognized by most commercially available robotic bar code readers.

Features of E-Gel gels:

  • High-throughput analysis—contains 48 sample lanes and 4 marker lanes per gel
  • Automation compatible—suitable for use with multi-channel pipettors and commonly used 8- and 12-pin liquid handling robots
  • Scalable—resolve up to 192 samples in one run by combining up to four E-Base Mother and E-Base Daughter device units
  • Less hazardous choice—contains SYBR Safe DNA stain, a less hazardous alternative to ethidium bromide
  • High performance—detect 3 ng of sample DNA with separation time as little as ∼20 minutes

Less hazardous option

Choose gels with SYBR Safe DNA stain to minimize exposure to hazardous and mutagenic factors such as ethidium bromide and UV. Precast E-Gel agarose gels with SYBR Safe stain, combined with a blue-light trans-illumination, offer better sample integrity and a less hazardous work environment. Unlike ethidium bromide, the DNA stain most commonly incorporated into agarose gels, SYBR Safe DNA Gel Stain is a non-toxic, non-mutagenic DNA stain that is less hazardous for the user, less hazardous for the environment, and can save institutional overhead costs for disposal.

Fast and convenient analysis

E-Gel agarose gels enable fast and high-performance analysis with a detection sensitivity of 3 ng sample DNA per band and a separation time three times faster than that of conventional pour-your-own gels. Each E-Gel agarose gel contains agarose, electrodes, SYBR Safe DNA stain, and a bufferless ion exchange system packaged inside a dry disposable cassette. E-Gel technology does not require any gel or buffer preparation or gel staining steps. Just load your samples and run.

Running and imaging devices

High-throughput E-Gel agarose gels require the Invitrogen E-Base Electrophoresis Device for gel running.

Available in a variety of gel formats

E-Gel agarose gels are available in variety of gel percentage, stain, and well formats. The high-throughput E-Gel 96 and 48 agarose gels with SYBR Safe stain are available in 1%, 2%, and 4% gel percentages.

    Frequently Asked Questions (FAQs)

    My E-Gel agarose gel has speckles when viewed in the imager. What should I do?

    Here are some suggestions:

    - Try cleaning the cassettes with alcohol and Kimwipes wipers.
    - Try cleaning the camera lens.
    - Try to adjust the exposure time and brightness options of the documentation system you are using.

    My sample is leaking from the wells when running my E-Gel agarose gels. What happened?

    Please ensure that you have not overloaded the well and that the wells were not damaged during comb removal.

    I accidentally stored my E-Gel agarose gels at 4 degrees C instead of room temperature. Can I still use them?

    While we recommend storage at room temperature, these gels will still be usable. Bring the gels to room temperature prior to the run for optimal conditions.

    Are there robotic scripts for running E-Gel 48/96 or E-PAGE 48/96 gels?

    Robotic scripts for running E-Gel 96 Agarose Gels and E-PAGE 96 Gels on Beckman Coulter's Biomek FX workstation can be found on our website at: www.thermofisher.com/egels (click the Labware Definitions link in the left navigation pane).

    What loading buffer should I use for my E-Gel agarose gels?

    Loading buffer is optional. Samples can be loaded directly into the wells if no buffer is used, or you can dilute them with deionized water or TE buffer. If you want to use a loading buffer, please see the recipes below:

    E-Gel agarose gels (including EX)
    10 mM Tris-HCl, pH 7.5
    1 mM EDTA
    0.005% bromophenol blue
    0.005% xylene cyanol FF
    E-Gel CloneWell II and E-Gel SizeSelect II agarose gels
    10 mM Tris-HCl, pH 7.5
    1 mM EDTA

    Alternatively, you can use 10X BlueJuice Gel Loading Buffer or TrackIt Loading Buffer. Dilute this buffer 50- to 200-fold to obtain optimal results with E-Gel agarose gels.

    How do I acquire and analyze data for my E-Gel agarose gels?

    We offer our E-Editor Software, which can help you align images after a gel run. The E-Editor 2.0 Software is only available for PCs, but the older E-Gel 96 Editor software is still available for the Mac operating system and can align images from E-Gel 96 and E-PAGE 96 agarose gels. However, the original software is not compatible with E-Gel 48 or E-PAGE 48 agarose gels. Please go to www.thermofisher.com and enter "E-Editor software" in the main search to download the E-Editor Software. You can use the E-Gel Imager System for data analysis.

    What is the difference between the EG and EP program for the E-Base system?

    The EG program is to run E-Gel 96 and 48 gels, while the EP is to run the E-PAGE 96 and 48 gels.

    How do E-Gel 48 agarose gels and E-Gel 96 agarose gels work?

    E-Gel 48 and E-Gel 96 gels contain a proprietary neutral-pH internal buffer system with special high capacity and low conductivity features. There are no ion exchange matrices.

    What are some of the important differences between the low-throughput and high-throughput E-Gel agarose gel systems?
    p>High-throughput E-Gel agarose gels have staggered wells, and are based on a neutral-pH internal buffer system as opposed to an ion exchange matrix. High-throughput E-Gel agarose gels cannot be opened, and should be run on the E-Gel E-Base system.
    I do not have enough samples to fill all wells in my E-Gel agarose gel. Can I leave some wells empty?

    If you do not have enough samples to use all the wells, fill each empty well with the same volume of water as the loaded samples. For E-Gel CloneWell II agarose gels and E-Gel SizeSelect II agarose gels, it is important to add the water according to the respective manual.
    Do you have a protocol for RNA electrophoresis on your E-Gel agarose gels?

    Our E-Gel agarose gels can be used for either DNA or RNA separation. RNA separation occurs under non-denaturing or denaturing conditions. Please note, our gels are not QC tested for the presence of RNases. See our suggestions below for running your non-denaturing or denaturing samples:

    Non-denaturing conditions
    1. Mix RNA sample with 15 µL of RNase-free water.
    2. Do not heat. Load the entire sample onto the E-Gel agarose gel.
    3. Electrophorese for 30 min.

    Denaturing conditions
    1. Mix 15 µL of RNA loading buffer with 1-5 µL of RNA (1-5 µg).
    2. Heat samples at 65 degrees C for 10 min to denature RNA.
    3. Place samples on ice immediately after heating.
    4. Load entire sample onto E-Gel agarose gel.
    5. Electrophorese for 30 min.

    Note:
    - The only denaturing agent that is compatible with the E-Gel system is formamide, 50-95%. Heating the sample for 5 min at 65 degrees C should be sufficient for denaturing. Using other denaturing agents like glyoxal, formaldehyde, or urea will result in very poor separation and band morphology on E-Gel agarose gels.
    - Additionally, we do not recommend running samples with RNA loading buffer on the same gel as samples loaded with water.
    - E-Gel EX Double Comb agarose gels and E-Gel Double Comb agarose gels with SYBR Safe stain have not been tested for use in RNA applications.

    I would like to take the gel out of the E-Gel agarose gel cassette. How can I do this?

    We recommend using the E-Gel Opener (Cat. No. G530001) for the SYBR and ethidium bromide E-Gel agarose gels. The E-Gel EX agarose gels, E-Gel SizeSelect agarose gels, and E-Gel GO! agarose gels can be opened with the Gel Knife (Cat. No. EI9010). We do not recommend opening the E-Gel 48 agarose gels or the E-Gel 96 agarose gels.
    What makes E-Gel agarose gels bufferless?

    To create a bufferless system, each E-Gel cassette contains two unique ion exchange matrices that lie between the running gel and the electrodes. The ion exchange matrices provide a buffer-ion reservoir that supplies a continuous flow of Tris, acetate, and dye ions throughout the gel. This patented technology results in a sustained electric field with enhanced buffering capacity. E-Gel gels thus eliminate the need for you to prepare and dispose of liquid buffer, thus saving time and waste.
    What buffer should I use for my E-Gel agarose gel electrophoresis experiments?

    The E-Gel agarose gel system is a precast bufferless TAE system that uses ion exchange matrices. The gels themselves are enclosed within a semi-UV-transparent cassette. This patented technology results in a sustained electric field with enhanced buffering capacity. E-Gel gels thus eliminate the need for you to prepare and dispose of liquid buffer, thus saving time and waste.
    Do I need to pre-run my E-Gel agarose gels?

    Pre-run is no longer necessary for any of our E-Gel agarose gels.
    Can E-Gel agarose gels be used with RNA samples?

    E-Gel agarose gels are routinely used in-house in R&D and manufacturing for RNA analysis with excellent results. However, the gels are not guaranteed to be “RNAse-free”. The manufacturing process is designed to avoid contamination of any type, but not RNAses specifically.

    If you do want to try it, any loading buffer that would be used for non-denaturing RNA electrophoresis should be fine for E-Gel agarose gels. Depending on your application, these gels may or may not be suitable for use.

    Can I run E-Gel agarose gels longer than recommended

    Do not run E-Gel agarose gels longer than 40 min for the single comb gels or longer than 20 min for the double comb gels as longer run times will cause ions to get depleted and will damage the gel. Do not run E-Gel 48 agarose gels longer than 30 min or E-Gel 96 agarose gels longer than 20 min.
    What is the shelf-life of an E-Gel agarose gel?

    All E-Gel gels are labeled with expiration dates.
    My E-Gel agarose gel is not running evenly. I am getting poor resolution or smearing of bands. What might be the problem?

    Potential problems include:
    - Loading too much DNA. Do not load more than the recommended amount.

    - Samples with a high salt concentration. Samples containing > 50 mM NaCl, 100 mM KCl, 10 mM acetate ions, or 10 mM EDTA will cause loss of resolution.

    - Samples may have been diluted in TAE instead of TE or water.

    - Samples may have been pre-run; pre-running is not recommended for any of our E-Gel agarose gels.

    - Sample was not properly loaded or had a very low volume of sample loaded. Load the recommended sample volume based on the gel type and loading method. For proper band separation, we recommend keeping sample volumes uniform.

    - Bubbles may have been introduced while loading the samples. Bubbles will cause band distortion. Load deionized water or TE into any empty wells, and avoid introducing bubbles.

    - A longer electrophoresis run time was used. Do not run the gel longer than the recommended time for each gel type. Longer run times cause an increase in the current, resulting in poor band migration or a melted gel. We recommend that you run single comb gels for 25-30 min (double comb gels 15-20 min) for straighter patterns. Do not run single comb gels longer than 40 minutes (20 minutes for double comb), or the gel will be damaged and resolution will be poor.

    - Voltage or current too high. This should not be an issue with the E-Gel PowerBase power supply, which is pre-set with the proper conditions. However, researchers using the old E-Gel Base (the one that plugged into a separate power supply) should ensure that they run the gel at 60 to 70 volts (constant voltage) or 40-50 mA (constant current). Do not allow the current to exceed 60 mA.

    - For E-Gel 96 Agarose Gels being run on an E-Base device, be sure you are running on the “EG” program rather than the “EP” program designed for E-PAGE gels.

    - The gel was not electrophoresed immediately after sample loading (for best results, run gel within 1 min of loading).

    - The gel may have been used beyond its expiration date. Check the expiration date.

    What grade of agarose is used in the E-Gel agarose gels?

    The agarose used in the 0.8%, 1.2% and 2% E-Gel agarose gels is molecular biology grade, with a normal melting point and less than 0.25% ash content. For the 4% E-Gel agarose gels, we use a special high-resolution agarose.
    What buffer is used in the E-Gel agarose gel system?

    The E-Gel agarose gel system uses TAE buffer.
    Can I use the E-Gel Power Snap Electrophoresis Device (Cat. No. G8100) to image my own pour-your-own gels?

    We do not recommend using the E-Gel Power Snap Electrophoresis Device to image pour-your-own gels.
    Can I use the E-Gel Power Snap Electrophoresis Device (Cat. No. G8100) to run my own pour-your-own gels?

    We do not recommend using the E-Gel Power Snap Electrophoresis Device to run pour-your-own gels.
    Is E-Gel software compatible with Windows 10?

    Yes, both the E-Gel GelCapture Acquisition Software and E-Gel GelQuant Express Analysis Software applications are compatible with Windows 10; however, the E-Gel GelQuant Express Analysis Software will require the purchase of an E-Gel Imager Quantitation USB dongle (Cat. No. 4466610):

    Note: Please make sure that you download the correct version of the E-Gel GelCapture Software based on the serial number of your instrument.

    How can I adjust the voltage on the E-Gel Power Snap Electrophoresis Device?

    Each program on the E-Gel Power Snap Electrophoresis Device is optimized to obtain the best possible results. The device does not offer user-adjustable voltage functionality.

    I can't see any of my bands on my E-Gel agarose gel when I turn on the blue light. What should I do?

    Follow recommended DNA dilutions and leave the gel to cool down on the bench or for a few minutes in the fridge. Please check troubleshooting tips provided in the manual.
    Can I run E-Gel agarose gels more than once?

    No. E-Gel agarose gels have enough buffering capacity for one run only. Performance will be impaired with multiple runs.
