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, fatty acid-free, US-Origin ≥98 %, fatty acid-free, for biochemistry and molecular biology
Highly pure albumin, prepared from blood of cattle certified for US-origin.
Albumin, fatty acid-free, US-Origin, may well be used for blocking of all assays regarding membrane proteins, or other approaches aiming for fatty acid-associated proteins. It is also well suited for stabilisation of antibodies, enzymes or fatty acids. Albumin, fatty acid-free, US-Origin, shows exceedingly low content of endotoxins and IgGs, making it a useful reagent for cell biology also.
BSA, fatty acid-free, US-Origin is particularly recommended if the use of albumin with certified US-Origin is dictated by process regulations.
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.
Tested for very low fatty acid concentration.
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.
