Product details
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, NZ-Origin ≥98 %, sulfhydryl blocked, protease-free, IgG-free
High quality albumin originating from Australia or New Zealand.
By blocking the thiol groups, the polymerisation of the albumin molecules is very efficiently prevented, which can occur during the storage of powder and solution and change the properties of the albumin. The albumin remains stable over time as a monomer and can, therefore, be used very well for reproducible laboratory assays. Due to its low IgG and protease content, the albumin is excellent for all immunoassays such as WESTERN or ELISA and as a stabilising reagent for proteins, antibodies etc. Furthermore, the Albumin, sulfhydryl-blocked, NZ-Origin is recommended for all thiol or sulfur sensitive assays.
Tested for the presence of free sulfhydryl groups, proteases and IgGs.

General information
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 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.
