Invitrogen™ IGFBP2 Human ELISA Kit

Beschreibung

The Human Insulin-like Growth Factor Binding Protein 2 (Hu IGFBP2) ELISA quantitates Hu IGFBP2 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu IGFBP2. Principle of the method The Human IGFBP2 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.

IGFBP2 (insulinähnliches Wachstumsfaktor-bindendes Protein 2) ist ein Mitglied der ISGBP-Familie, die verschiedene IGFs binden. IGFBP2 wird in einem breiten Spektrum von Krebserkrankungen überexprimiert, einschließlich Gliom, Prostatakrebs, Synovialsarkom, Neuroblastom, Darmkrebs, Nebennierenkrebs, Lungenkrebs, Wilms-Tumor und Hepatoblastom. Die Überexpression von IGFBP2 korreliert auch mit der Aggressivität einiger Tumoren. IGFBP2 aktiviert die Expression der Matrixmetalloprotease 2, die zur Zellinvasivität beiträgt.
