Recommended as blocking and stabilising reagent in all antibody-mediated detection systems.
€72.90/Pack Qty.
excl. VAT. | 10 g per Pack Qty.
Art. No. 1ET9.1
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, US-Origin ≥98 %, protease-free, IgG-free
Albumin, highly purified and tested for the presence of immunoglobulins (IgGs)
The Albumin, IgG-free, US-Origin is especially recommended to stabilize antibody solutions and as blocking reagent in all assays working with antibodies. Due to its particularly low protease content, it is also well suited for use in all other protein assays that could be interfered with by protease presence.
Tested for the presence of 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.
