Anti-BFGFR antibodies are protein reagents that detect specific antigens. The BFGFR antigen is another term for the human protein fibroblast growth factor receptor 1, encoded by the FGFR1 gene. The protein is reported to be a tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of embryonic development, cell proliferation, differentiation and migration. Canonically, it has an amino acid length of 822 residues and a mass of 91.9 kilodaltons. Its subcellular localization is in the cell membrane, nucleus, cytoplasmic vesicles, and cytoplasm and it is notably expressed in astrocytoma, neuroblastoma and adrenal cortex cell lines. The BFGFR protein is a member of the Tyr protein kinase protein family. Other alias names for BFGFR include CD331. Some BFGFR antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
