Bovine Serum Albumin (BSA) Fraction V,, US-Origin, min. 96 %, for biochemistry, and molecular biology, Molar mass (M) ~66 000 g/mol, Storage temp. +4 °C, CAS No. [9048-46-8], EG-Nr. 232-936-2

For purification of this Albumin an extensive heat-shock/diafiltration method is used, which has been shown to bring more highly purified products than the standard process acc. to Cohn. The process is taking place in a closed system.

Molar extinction coefficient: 4,4x10⁴ L x mol^-1 x cm^-1 (acc. to 0,667 L x mol^-1 x cm^-1 for a 0,1 % solution).

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 are proteins yielded from blood, which function as binding and transport proteins in blood circulation. Depending on the preparation process, the albumins contain different quality and quantities of metabolic products, enzymes, peptides, fatty acids, vitamines, etc. and are suitable for different applications.

Heatshock albumin

For purification of this Albumin an extensive heat-shock/diafiltration method is used, which has been shown to bring more highly purified products than the standard process acc. to Cohn. The process is taking 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.
