Anti-FGF-4 antibodies enable researchers to detect and measure the FGF-4 antigen in biological samples. This target is a reported synonym of the FGF4 gene, which encodes fibroblast growth factor 4. This protein is known to function in organ morphogenesis and cell differentiation, among other biological roles. The human version of FGF-4 has a canonical amino acid length of 206 residues and a protein mass of 22 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein. Other names for this target antigen include HBGF-4, HST, and HST-1. Western Blot is a widely used application for the FGF-4 antibodies listed below. In addition, ELISA is also a common application.
