Anti-Cx30.3 antibodies enable researchers to detect and measure the Cx30.3 antigen in biological samples. This target is a reported synonym of the GJB4 gene, which encodes gap junction protein beta 4. This protein is known to function in cell to cell signaling and the sensory perception of smell, among other biological roles. The human version of Cx30.3 has a canonical amino acid length of 266 residues and a protein mass of 30.4 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the skin, oral mucosa, lung, and hair. Cx30.3 is a member of the Connexin protein family. Indicated applications for Cx30.3 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
