Vector Laboratories Streptavidin/Biotin Blocking Kit 36 ml
Streptavidin/Biotin Blocking Kit (SP-2002) blocks all endogenous biotin, biotin receptors, and streptavidin binding sites present in tissues. This kit is designed for use with streptavidin detection systems if streptavidin or biotinylated reagents bind non-specifically to tissues or proteins. This blocking kit consists of 18 ml of streptavidin and 18 ml of biotin in convenient dropper bottles. The streptavidin solution is applied first (mixed with normal blocking serum), followed by the biotin solution.
