Blocker™ Casein

Blocker Casein is a ready-to-use solution of purified casein for blocking steps in western blot, ELISA, IHC, and nucleic acid detection methods. Blocker Casein is 1% (w/v) casein, which corresponds to the optimal concentration for most applications.

Features of Blocker Casein include:
• Purified casein—single-protein blocking buffer provides fewer chances of cross-reaction with assay components than serum or milk solutions
• Easy to use—1% casein solution is ready to use; can be diluted further as needed
• Safe—stable, thimerosal-free formulation
