Anti-FGFBP2 antibodies are used in the immunodetection of the protein fibroblast growth factor binding protein 2. In humans, the canonical protein has a reported length of 223 amino acid residues and a mass of 24.6 kDa. It has been described to be a secreted protein. It is reported to be expressed in serum, peripheral leukocytes and cytotoxic T-lymphocytes, but not in granulocytes and monocytes. A member of the Fibroblast growth factor-binding protein family, FGFBP2 is known to be involved with cell to cell signaling. Synonyms for this target antigen include FGF-binding protein 2, HBp17-RP, HBp17-related protein, and 37 kDa killer-specific secretory protein. FGFBP2 gene orthologs have been reported in the frog, chimpanzee and chicken species. Some FGFBP2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
