Invitrogen™ I-Block™ Protein-Based Blocking Reagent 
Highly purified Casein-based blocking reagent. Thermo Scientific I-Block Protein-Based Blocking Reagent provides superior blocking compared to both dried milk and BSA.
Supplier: Invitrogen™ T2015
Description
- Biotin-free
- Tested in assays using Tropix substrates and alkaline phosphatase conjugates
- Useful as blocking reagent in membrane-based and immunoassay applications
- Suggested working
- concentration is 0.2% (w/v) for detection of nucleic acids on neutral or positively-charged nylon membranes and for immunoassays and protein detection on membranes (nitrocellulose, PVDF, or neutral nylon)
- Concentration of 3% is recommended for protein detection on positively-charged nylon membrane (such as TropilonPlus™ membrane)
Preparation:
Prepared in either Tris- or phosphate-buffered saline buffer with heating (40° to 50°C).
Applications:
Can be used with Western-Light™, Western-Light Plus™, Western-Star™, ELISA-Light™, Southern-Light™, and Southern-Star™ Detection Systems.
