| Biochem/physiol Actions: | Human serum albumin (HSA) plays a vital role in the regulation of the colloidal osmotic pressure of blood. It also aids in the maintenance of metal ion homeostasis, including the transport and storage of transition metals. The high binding capacity of HSA with a wide range of ions and molecules makes it an effective molecular cargo and nano vehicle used in biophysical, clinical, and industrial fields. Human and bovine albumins contain 16% nitrogen and are often used as standards in protein calibration studies. It is used as a blocking agent in Western blots or enzyme-linked immunosorbent assay (ELISA) applications. Globulin-free albumins are suitable for use in applications where no other proteins should be present (e.g., electrophoresis). |

| Features and Benefits: | • Easily crystallized and contain an excess of acidic amino acids. • Serum and plasma albumin is carbohydrate-free and comprises 55-62% of the protein present • Due to its high charge to mass ratio albumin binds water, Ca2+, Na+, K+, fatty acids, bilirubin, hormones, and drugs. • The free hydrophobic region of fatty acid-free albumins helps to solubilize lipids in tissue culture |
| General description: | Human serum albumin (HSA) is a monomeric, globular, and α-helical protein that constitutes a major part of human blood plasma proteins. This single-chain polypeptide protein contains 585 amino acid residues and 17 internal disulfide bridges and one free cysteine. |
| General description: | Human serum albumin undergoes three different post-translational modifications: oxidation, glycation, and S-nitrosylation. Modifications usually occur on the surface of the globular protein, and do not significantly affect conformation. However, modification strongly affects binding of fatty acids and drug molecules. |
