Yes, Power Blotter Select Transfer Stacks are compatible with immunofluorescence detection.

Yes, both PVDF and nitrocellulose membranes are compatible with the Power Blotter System/Power Blotter XL System. You can use 0.2 µm and 0.45 µm pore size membranes. Our Power Blotter Pre-cut Membranes and Filters (PVDF and nitrocellulose) come with 0.45 µm pore size membranes. Our Power Blotter Select Transfer Stacks (PVDF and nitrocellulose) come with 0.2 µm pore size membranes.

This may be due to salt deposited on moving parts inside the cassette. We recommend rinsing the cassette top and bottom under warm water while removing any sticky salt residue with a gloved hand. Briefly rinse with deionized water and place in a rack to dry. For more thorough cleaning, immerse the unassembled cassette in warm water and use a gloved hand or clean sponge to remove any sticky salt residue. Rinse with deionized water and place perpendicular in a rack to dry.
Note: Failure to keep the cassette top (cathode) and bottom (anode) clean will result in the sticking of moving parts and lead to poor transfer efficiency.

Yes. You may use the same method that was used with the G2 Fast Blotter: https://www.thermofisher.com/us/en/home/life-science/protein-biology/protein-biology-learning-center/protein-biology-resource-library/protein-biology-application-notes/transfer-emsa-gels-using-g2-fast-blotter.html

No, revalidation is not necessary. The firmware is the same and the blotting efficiency is the same.

You can use your own consumables (membrane, filter paper with 2.48 mm thickness, and buffer) for standard semi-dry transfer on the Power Blotter System/Power Blotter XL System following the parameters recommended on page 20 of the Power Blotter System User Guide (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0017053-PowerBlotterSystem-UG.pdf).

For fast semi-dry transfer on the Power Blotter System/Power Blotter XL System, you can use your own membrane and filter paper (with 1.8 mm thickness), however, the Power Blotter 1-Step Transfer Buffer or the Pierce 1-Step Transfer Buffer would need to be used.

Yes, but you need to ensure that the total thickness of the filter paper stack on either side of the gel/membrane does not exceed 1.8 mm.

Yes, utilization of the Power Blotter 1-Step Transfer Buffer (5X) allows fast transfer (within 5 min for low MW proteins/within 7 min for mixed range MW proteins/within 10 min for high MW proteins). The Power Blotter can also be used with the Pierce 1-Step Transfer Buffer (Cat. No. 84731, 84731X5, or 84742) for fast transfer.

Yes, the Power Blotter System/Power Blotter XL System is an open system and you can use your own transfer buffer. However, keep in mind that your own transfer buffer will result in a prolonged transfer time (˜60 min), whereas a fast transfer (5-10 min) can be achieved using the Power Blotter 1-Step Transfer Buffer (5X) or the Pierce 1-Step Transfer Buffer.

Yes, you can order the Power Blotter Cassette XL (Cat. No. PB0003).
Note: The Power Blotter Cassette (Cat. No. PB0002) is not compatible with the G2 Fast Blotter.

The Power Blotter Cassette (Cat. No. PB0002) is designed to blot 1-2 mini gels at a time or 1 midi gel and the Power Blotter Cassette XL (Cat. No. PB0003) is designed to blot 1-4 mini gels or 1-2 midi gels at a time. Both cassettes can be used with the Power Blotter. On the other hand, the traditional G2 Fast Blotter is only compatible with the Power Blotter Cassette XL (Cat. No. PB0003); the Power Blotter Cassette (Cat. No. PB0002) will not work with the G2 Fast Blotter.

You can purchase the Power Blotter Station (Cat. No. PB0010) and the G2 Fast Blotter cassette is compatible with it. The new Power Blotter System is designed for Western transfer alone and does not have a staining module; therefore, the G2 Fast Blotter staining cassette cannot be used on the Power Blotter Station.

We do not offer a staining cassette for the Power Blotter System/Power Blotter XL System but it can be programmed to stain gels. Please see the user guide for our Pierce Mini/Midi Gel Power Staining Kit (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0017799_22839_22840_powerstain_midi_minigel_UG.pdf) for how to create a Custom Staining Method.

No, 1-2 mini gels and 1, 2, or 4 mini gels can be transferred at the same time with the same transfer efficiency using the Power Blotter System and Power Blotter XL System, respectively.
