Rat INS (Insulin) ELISA Kit (E-EL-R3084)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat INS. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat INS and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat INS, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 5 nm. The OD value is proportional to the concentration of Rat INS. You can calculate the concentration of Rat INS in the samples by comparing the OD of the samples to the standard curve.

Insulin and the IGFs are members of the insulin family of molecules. IGF-I and II are structurally homologous to proinsulin,and can be thought of as taking the shape of an exaggerated,inverted letter G.Intrachain disulfide bonds link sections of the G.The single chain insulin propeptide consists of a 30 amino acid B chain (aa 2554),a C-peptide (aa 5589),and a 21 aa A chain (aa 90110).Removal of the C-peptide by proteolysis enables the formation of mature Insulin,a disulfidelinked heterodimer of the A and B chains.Circulating C-peptide levels are elevated in hyperinsulinism,obesity,and type II diabetes.
