General description

Human serum albumin (HSA) is an unglycosylated, soluble, and globular monomeric protein. It is abundantly found in the plasma, with a multidomain comprising three homologous domains, called I, II, and III. Three of these domains have subdomains A and B with common structural motifs. The HSA gene is localized on the human chromosome 4q13.3.

Application

Albumin, human serum, fraction V, high purity has been used to determine the binding affinity of nanobody α human serum albumin (HSA) to HSA and injected to detect the signals of tandem binding of human interleukin (IL-21R), IL-21-αHSA, and HSA. It has also been used to study the effects of fetuin-A phosphorylation on calciprotein particles (CPP) uptake.

Biochem/physiol Actions

Human serum albumin (HSA) plays a major role as a carrier protein for fatty acids, thyroid hormones, and steroids. It is involved in stabilizing extracellular fluid volume. HSA is used to treat hemodialysis, acute liver failure, chronic liver disease. It serves as an excipient for vaccines and therapeutic protein drugs. HSA is implicated in biological applications, including ligand trapping, nano delivery of drugs, and fusion proteins.
