Synonyms: BSA, Bovine albumin
Albumin bovine is a single polypeptide chain consisting of about 583 amino acid residues and no carbohydrates. At pH 5-7 it contains 17 intrachain disulfide bridges and 1 sulfhydryl group.
Albumin is used to solubilize lipids, and is also used as a blocking agent in Western blots or ELISA applications. Globulin free albumins are suitable for use in applications where no other proteins should be present (e.g., electrophoresis).
This product was derived from bovine blood collected at a USDA licensed facility. The cattle received ante- and post-mortem health inspection under a veterinarian's supervision and were apparently free from infectious and contagious diseases. All donor animals were sourced from the United States. Blood collection records were incorporated into a manufacturing batch documents.
Certain conformational and primary-sequence epitopes of BSA are suspected allergens in human beef and milk allergies.
