Product Description

Bovine Serum Albumin-blocking solution (Catalog#: BSA-blocking) is 25% solutions of high-quality bovine serum albumin. It is suitable for Western blotting and immunohistochemistry (IHC). It is ready to use, no waiting for powder to dissolve with the concentrated formulation. As a single purified protein exists, BSA-blocking has fewer chances of cross-reaction with assay’s components than serum or milk solutions. BSA-blocking can also stabilize your antibodies and your protein of interests.  It is prepared in PBS, TBS, and proteinase-free water formulations to suit for a variety of applications.


Take 1 mL/0.4 mL of this BSA-blocking into 25 mL/10 mL of 1X PBST/TBST to make working blocking solution, or membrane blotting solution by adding your antibody into this 1%BSA-1X PBST/TBST solution.  Your primary antibody in this solution can be stored at 2-8°C by adding 0.1 % sodium azide (the final concentration, we have 100X stock, sodium azide stock can be provided for free when you order our BSA-blocking), and it can be used at least 5 times for membrane blotting.


Storage temperature: 2-8°C.
