>98%, Powder
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.
Applications
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).
Preparation Method
Heat-Shocked Fractionate.
Analysis Note
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.
Biochem/physiol Actions
Certain conformational and primary-sequence epitopes of BSA are suspected allergens in human beef and milk allergies.
