Bovine Serum Albumin Bovine serum albumin (BSA) is typically used at a 1% to 3% con-centration. BSA is inexpensive and can be stored dry or as a sterile solution at 4°C. The use of BSA as a blocking reagent is well docu-mented and has been proven to be a good blocker of non-specific protein-surface binding on medium and high binding surfaces, as
IgG-Free, Protease-Free Bovine Serum Albumin. Bovine serum albumin (BSA) is used extensively as a carrier protein to dilute antibodies and as a general protein blocking agent in immunoassays and immunodetection protocols. If BSA is the desired diluent or blocking reagent for your assay it’s important to use BSA that is suitable for the purpose.

Bovine serum albumin (BSA) is straightforward and easy to use. I use BSA (5%) in my blocking buffer solution to reduce non-specific binding during immunohistochemistry. BSA goes into solution well, but it gets foamy very easily. To reduce this, stir the solution slowly until the BSA is dissolved.
Bovine serum albumin (BSA)
Protein blockers are a permanent blocking solution, and plates only need to be treated once for effective blocking. Protein blockers can also be added to the diluents used in subsequent steps to further reduce background signal. The most common blocking proteins include: bovine serum albumin (BSA), nonfat dry milk, and whole normal serum.
The buffer blocks all potential binding sites of nonspecific interaction and reduces the background signal, improving the signal-to-noise ratio. The Synthetic Blocking Buffer, ELISA reduces the risk of false positive reactions in the assay, while avoiding the current safety hazards related to the use of bovine biological material, for instance BSA.
