Description

General description

Human serum albumin (HSA) is an unglycosylated, soluble, and globular monomeric protein.[1] It is abundantly found in the plasma,[2] with a multidomain comprising three homologous domains, called I, II, and III.[2][3] Three of these domains have subdomains A and B with common structural motifs. The HSA gene is localized on the human chromosome 4q13.3.[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.[4] It has also been used to study the effects of fetuin-A phosphorylation on calciprotein particles (CPP) uptake.[5]

Biochem/physiol Actions

Human serum albumin (HSA) plays a major role as a carrier protein for fatty acids, thyroid hormones, and steroids.[1] It is involved in stabilizing extracellular fluid volume.[1] HSA is used to treat hemodialysis, acute liver failure, chronic liver disease.[2] It serves as an excipient for vaccines and therapeutic protein drugs.[1] HSA is implicated in biological applications, including ligand trapping, nano delivery of drugs, and fusion proteins.[2][1]
