Anti-CD333 antibodies enable researchers to detect and measure the CD333 antigen in biological samples. This target is a reported synonym of the FGFR3 gene, which encodes fibroblast growth factor receptor 3. This protein is known to function in cell to cell signaling and chondrocyte differentiation, among other biological roles. The human version of CD333 has a canonical amino acid length of 806 residues and a protein mass of 87.7 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles, ER, and cell membrane of cells and notably expressed in many tissues, such as the hippocampus and skin. Other names for this target antigen include ACH and CEK2. ELISA, Western Blot, and Immunohistochemistry are common applications for CD333 antibodies.
