To block nonspecific background staining observed during immunostaining.
Background Blocker is unique serum-free blocking solution used to reduce nonspecific background staining. It is a universal blocking agent which eliminates the need to match species with the link antibody. This blocking reagent has been shown to be more superior than serum-based blocking solutions. In addition to immunihistochemistry, Background Blocker can also be used for ELISA and Western Blot techniques.
