Description
Bovine Serum Albumin (BSA) Fraction V is a purified albumin reagent intended for immunology and life-science applications, provided at min. 98 % purity under CAS number 9048-46-8 and EG nr. 232-936-2. This Fraction V grade is protease-free and characterised as very low endotoxin, and originates from New Zealand (NZ-Origin), making it suitable where reduced proteolytic activity and controlled endotoxin levels support sensitive assay work. The approximate molar mass is 66 000 g/mol. Typical uses include blocking, protein stabilisation and carrier functions in immunodetection, blotting and related protocols that benefit from a clean albumin background. The material is This BSA Fraction V from manufacturer Carl ROTH combines NZ origin with protease-free and very low-endotoxin attributes for laboratories that need a defined Fraction V albumin in immunodetection and broader life-science workflows without unnecessary process-related contaminants.

Questions about Bovine Serum Albumin (BSA) Fraction V, NZ-Origin, 1 g, glass, >=98 %
What is this article?
Bovine Serum Albumin (BSA) Fraction V, NZ-Origin, 1 g, glass, >=98 % is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Enzymes & substrates, inside Biochemicals & reagents, in Microbiology lab supplies.
An enzyme is sold by activity, in units defined by a stated reaction, not only by milligrams. Source and specific activity are the specification. A substrate is the molecule that enzyme converts, often a chromogenic one so the reaction can be seen. Units from two suppliers are comparable only when the definition matches.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
