Bio-activity : Insulin Like Growth Factor Binding Protein 2 (IGFBP2) is a menber of IGF binding proteins (IGFBPs) family. IGF binding proteins (IGFBPs) are proteins of 24 to 45kDa. Inhibits IGF-mediated growth and developmental rates. 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. Besides, Insulin Like Growth Factor 2 (IGF2) has been identified as an interactor of IGFBP2, thus a binding ELISA assay was conducted to detect the interaction of recombinant mouse IGFBP2 and recombinant mouse IGF2. Briefly, IGFBP2 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100μL were then transferred to IGF2-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-IGFBP2 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37°C. Finally, add 50µL stop solution to the wells and read at 450nm immediately. The binding activity of IGFBP2 and IGFBP2 was shown, and this effect was in a dose dependent manner.
