Invitrogen™ IGFBP4 Human ELISA Kit

Beschreibung

The Human Insulin-like Growth Factor Binding Protein 4 (Hu IGFBP4) ELISA quantitates Hu IGFBP4 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu IGFBP4. Principle of the method The Human IGFBP4 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.

Dieses Gen ist Mitglied der Familie der insulinähnlichen Wachstumsfaktor-Bindungsproteine (IGFBP) und kodiert ein Protein mit einer IGFBP-Domäne und einer Thyroglobulin-Typ-I-Domäne. Das Protein bindet insulinähnliche Wachstumsfaktoren (IGFs) des Typs I und II und zirkuliert im Plasma sowohl in glykosylierter als auch in nicht-glykosylierter Form. Die Bindung dieses Proteins verlängert die Halbwertszeit der IGFs und verändert deren Interaktion mit Zelloberflächenrezeptoren.
