Product details
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).
Albumin Fraction V, US-Origin ≥96 %, for biochemistry and molecular biology
Highly pure albumin of Cohn's Fraction, prepared from blood of cattle certified for US-origin. Albumin Fraction V, 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 made of fresh bovine plasma by fractionation (Cohn method) and subsequent crystallisation from alcohol solution at a low temperature.
Available in large bulk format on request.

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).
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.
