Bovine serum albumin (BSA) is a small protein weighing 66 kDa, constituting about 50% of the total serum proteins. Due to its negative charge, BSA binds to water, salts, fatty acids, vitamins, and hormones, transporting these bound components between tissues and cells. Albumins are frequently used as stabilizers for other soluble proteins, such as labile enzymes.
Thanks to its high stability and minimal interference with biological activities, BSA is utilized in many biochemical applications, including immunochemistry, western blotting, and ELISA tests, where it is used as a blocking reagent.
The 30% BSA solution is a ready-to-use preparation for biochemical tests, sterilized by filtration.
