Kit Principle:
Aviva Systems Biology IGFBP4 ELISA Kit (Human) (OKCD00785) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for IGFBP4 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips). Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for IGFBP4 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration is read by absorbance at 450 nm and is quantitatively proportional to the amount of sample IGFBP4captured in well.

NCBI Gene Id:
Protein Name:
insulin-like growth factor-binding protein 4
Description of Target:
IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
