The Human Insulin like Growth Factor 1 (IGF 1) ELISA quantitates IGF 1 in serum and plasma.
Principle of the method
The Human IGF 1 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, where Human IGF 1 in the samples (or standards) binds to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) HRP linked antibody specific for Human IGF 1. Excess conjugate and unbound sample or standard are washed away from the plate. The substrate solution is added to each well, and the enzyme substrate reaction is terminated by the addition of a stop solution, turning the color yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The intensity of this signal is directly proportional to the concentration of Human IGF 1 present in the original specimen, which is determined by comparing the OD of the samples to the standard curve.

IGF1 (Insulin-like growth factor-1) is structurally and functionally related to insulin but has a much higher growth-promoting activity. A variety of cellular responses are induced by IGF1, including cell proliferation, differentiation, migration, and survival. Further, IGF1 is a polypeptide growth factor that stimulates the proliferation of a wide range of cell types in muscle, bone, and cartilage tissue. IGF1 stimulates glucose transport in rat bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regards to enhancing glucose uptake. In circulation, IGFs are predominantly bound to binding proteins (IGFBPs) which prolong the half-life of the IGFs and play a role in delivering them to target tissues. IGF-I is known as one of the most potent activators of the AKT signaling pathway which is known to be a stimulator of proliferation and an inhibitor of programmed cell death. Moreover, mature human IGF-I is 100% homologous with bovine and porcine proteins. Low levels of IGF1 have been linked to Alzheimer's disease. IGF1 is processed from a precursor, bound by a specific receptor, and secreted. Defects in the IGF1 gene are a cause of insulin-like growth factor 1 deficiency and several transcript variants encoding different isoforms have been found.
