Bovine Insulin EIA 牛胰島素檢測試劑盒背景介紹：

Mercodia Bovine Insulin ELISA provides a method for the quantitative determination of insulin in bovine serum and plasma.

Bovine Insulin EIA 牛胰島素檢測試劑盒SUMMARY AND EXPLANATION OF THE TEST

Insulin is the principal hormone responsible for the control of glucose metabolism. It is synthesised in the ?-cells of the islets of Langerhans as the precursor, proinsulin, which is processed toform C-peptide and insulin. Both are secreted in equimolar amounts into the portal circulation.The mature insulin molecule comprises two polypeptide chains, the A chain and the B chain. Thetwo chains are linked together by two inter-chain disulphide bridges. There is also an intra-chaindisulphide bridge in the A chain.Secretion of insulin is mainly controlled by plasma glucose concentration, and the hormone has anumber of important metabolic actions. Its principal function is to control the uptake and utilisation of glucose in peripheral tissues via the glucose transporter. This and other hypoglycaemicactivities, such as the inhibition of hepatic gluconeogenesis and glycogenolysis are counteractedby the hyperglycaemic hormones including glucagon, epinephrine (adrenaline), growth hormoneand cortisol.It is well known that ruminants show typical insulin resistance compared to monogastric animals.During lactation, glucose is effectively redirected to the mammary gland as a result of anincrease in insulin resistance in the peripheral tissue. Furthermore, the level of insulin secretionalso differs depending on the physiological states of dairy cattles (1-3).

Bovine Insulin EIA 牛胰島素檢測試劑盒PRINCIPLE OF THE PROCEDURE

Mercodia Bovine Insulin ELISA is a solid phase two-site enzyme immunoassay. It is based on thedirect sandwich technique in which two monoclonal antibodies are directed against separateantigenic determinants on the insulin molecule. During incubation, insulin in the sample reactswith peroxidase-conjugated anti-insulin antibodies and anti-insulin antibodies bound to themicrotitration well. After a simple washing step that removes unbound enzyme labelled antibody,the bound conjugate is detected by reaction with 3,3′-5,5′-tetramethylbenzidine (TMB). Thereaction is stopped by the addition of acid, giving a colorimetric endpoint that can be readspectrophotometrically
