Background Information:
Insulin, a 5.8 kD hormone is secreted by the islet beta cells in the pancreas.
This radioimmunoassay (RIA) measures & quantifies Insulin for use in Metabolism & Endocrine research.
Key Applications:
Application Notes:
Overnight, equilibrium incubation at 4º C. Sample volume 100 μL serum, plasma, or tissue culture media.

Entrez Gene Summary:
After removal of the precursor signal peptide, proinsulin is post-translationally cleaved into two chains (peptide A and peptide B) that are covalently linked via two disulfide bonds. Binding of this mature form of insulin to the insulin receptor (INSR) stimulates glucose uptake. A variety of mutant alleles with changes in the coding region have been identified. There is a read-through gene, INS-IGF2, which overlaps with this gene at the 5' region and with the IGF2 gene at the 3' region.
UniProt Summary:
FUNCTION: SwissProt: P01308 # Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
SIZE: 110 amino acids; 11981 Da
SUBUNIT: Heterodimer of a B chain and an A chain linked by two disulfide bonds.
DISEASE:SwissProt: P01308 # Defects in INS are the cause of familial hyperproinsulinemia [MIM:176730].
SIMILARITY: SwissProt: P01308 ## Belongs to the insulin family.
