Bovine Serum Albumin (BSA) Fraction V, US-Origin ≥96 %, for biochemistry and molecular biology

Highly pure albumin prepared from blood of cattle certified for US-origin. Albumin US-Origin may well be used for all standard assays where blocking with BSA is necessary, as well as for stabilisation of antibodies or enzymes. Many lots show exceedingly low content of protease and IgGs.
BSA, US-Origin is particularly recommended if the use of albumin with certified US-Origin is dictated by process regulations.

BSA is a soluble monomeric protein with a molecular weight of 66.5 kDa. It is synthesized in the liver and extracted from the blood of cattle. In the bloodstream it serves as a binding and transport protein. BSA is used as a standard in protein quantification, as a blocking reagent, as a satabilizer in molecular applications and as a nutrient additive in cell cultures.


Purification process

The purification of the BSA is carried out using a far-reaching heat shock/diafiltration method that produces higher purity albumins than the usual Cohn crystallization. The process takes place in a closed system.


Albumin, NZ-Origin is particularly recommended when procedural regulations require the use of albumin of guaranteed origin Australia or New Zealand.


BSA, US-Origin is particularly recommended if the use of albumin with certified US-Origin is dictated by process regulations.


Albumin of European origin is produced from blood of European cattle herds. It is excellent for use in all assays and products manufactured for regions outside the USA, Australia and New Zealand.
