The IBP3 ELISA kits listed below are analytical tools for measuring concentrations of IBP3 in various samples. IBP3 is an alternative name for the human IGFBP3 gene, which encodes the protein, insulin like growth factor binding protein 3. It has been mentioned that IBP3 plays a role in the apoptotic pathway and MAPK cascade signaling pathways, among other functions. Structurally, the IGFBP3 protein is 291 amino acid residues in length and 31.7 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is noted to be expressed by most tissues. This protein is known to be phosphorylated and glycosylated. Other names for this target antigen include BP-53 and BP-53.
