Anti-ACH antibodies are used in antigen-specific immunodetection in biological samples. The target ACH is a known alias name of the protein fibroblast growth factor receptor 3, encoded by the FGFR3 gene in humans. This 806-amino acid residue 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 cell proliferation, differentiation and apoptosis. It is localized to the cytoplasmic vesicles, ER, and cell membrane of the cell and features N-glycosylated, ubiquitinated and phosphorylated post-translational modifications. In terms of tissue expression, it is reported to be expressed in the brain, kidney and testis. Other synonyms for ACH include CD333 and CEK2. ELISA, Western Blot, and Immunohistochemistry are common applications for ACH antibodies.
