Bovine Serum Albumin – Zinc protocol

Bovine serum albumin (also known as BSA) is a serum albumin protein derived from cows, which is often used as a protein concentration standard in lab experiments. Among its 583 amino acid residues, it contains 17 intrachain disulfide bonds as well as one free thiol group, which can be used for site-specific labeling with a thiol-reactive (maleimide) fluorescent dye. Apart from fatty acids and a variety of small molecules in the blood, BSA is also associated with the transport of metal ions such as zinc (Zn2+).
