Protein solutions are used for blocking excess binding sites in ELISA, blotting, immunohistochemistry and other immunochemical applications. Each blocking solution will impart certain characteristics on the assay system.  

Our BLOK™ BSA is a 10% solution of BSA (Bovine Serum Albumin) that serves as a protein blocking agent. It does not contain endogenous biotin; therefore, it is compatible with biotin/avidin systems and results in high signal-to-noise ratios in most systems. It is robust and shows a lack of cross-reactivity.
Our BLOK™ BSA is supplied in your choice of buffer: either in our Phosphate Buffered Saline or our Tris Buffered Saline, both 10X concentrated solutions.



  • [10X] BSA solution
  • Convenient & Ready-to-use
  • Available in your choice of TBS or PBS buffers



  • For blocking Westerns, ELISA and dot Blots
