Invitrogen™ Insulin Rat ELISA Kit 

Description

The Rat Insulin ELISA quantitates Rt Insulin in rat serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Rt Insulin. Principle of the method The Rat Insulin solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Insulin is a peptide hormone secreted by beta cells of the pancreatic islets. It regulates carbohydrate, protein and lipid metabolism by enhancing membrane transport of glucose, amino acids, and certain ions. It also promotes glycogen storage, formation of triglycerides and synthesis of proteins and nucleic acids. Insulin is 51-amino acid polypeptide product produced from a precursor peptide, proinsulin. Proinsulin is post-translationally cleaved into two chains (peptide A and peptide B) that are covalently linked via two disulfide bonds and one molecule of C-peptide. Insulin deficiency results in diabetes mellitus, one of the leading causes of morbidity and mortality in the general population. Insulin is also present in tumors of b-cell origin such as insulinoma.
