Description
Principle of the Assay: The Human GDF15 ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human GDF15 in Cell Culture Supernatants, Serum, Plasma. This assay employs an antibody specific for Human GDF15 coated on a 96-well plate. Standards and samples are pipetted into the wells and GDF15 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human GDF15 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of GDF15 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Background: GDF-15 (Growth differentiation factor 15),also known as TGF-PL, MIC-1, PDF, PLAB, and PTGFB, is a protein belonging to the transforming growth factor beta superfamily that has a role in regulating inflammatory and apoptotic pathways in injured tissues and during disease processes. Using FISH, the MIC1 gene is mapped to 19p13.2-p13.1. Its expression in liver can be significantly up-regulated in during injury of organs such as liver, kidney, heart and lung. GDF15 showed increased expression and secretion during erythroblast maturation. GDF15 functions as an antiinflammatory cytokine by directly interfering with chemokine signaling and integrin activation
