Human Serum Albumin

General description

Anti-human serum albumin antibody, mouse monoclonal (mouse IgG2a isotype) is derived from the HSA-11 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mouse immunized with human serum albumin (HSA). Monoclonal anti-human serum albumin specifically recognizes human albumin derived from sera, plasma or liver cells.
HSA is encoded by the gene mapped to human chromosome 4q13.3. It is characterized with three homologous domains that assemble to form a heart-shaped molecule. HSA constitutes around 60-65% of total serum protein.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Other Notes

In order to obtain best results in different techniques and preparations we recommend determining optimal working concentration by titration test.

Biochem/physiol Actions

Human serum albumin (HAS) serves as a transport and depot protein for several endogenous ligands including fatty acids, hormones, steroids, bilirubin and heme. High intravascular concentration of HSA enables it to play an essential role in exerting colloid osmotic pressure and thereby to regulate the oncotic pressure and volume of blood. It also acts as an antioxidant and is required for exerting Donnan effect in the capillaries. Mutations in the gene is associated with the development of bisalbuminaemia or alloalbuminaemia. Deficiency of the gene leads to analbuminaemia.
