Thermo Scientific™ Blocker™ Casein in TBS, 1 L

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

• 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

Contents

• 1% (w/v) casein (Hammarsten grade) in 25mM Tris, 150mM NaCl, pH 7.4
