Anti-Arix antibodies enable researchers to detect and measure the Arix antigen in biological samples. This target is a reported synonym of the PHOX2A gene, which encodes paired like homeobox 2A. This protein is known to function in neuronal differentiation and the regulation of transcription, among other biological roles. The human version of Arix has a canonical amino acid length of 284 residues and a protein mass of 29.7 kilodaltons. It is reported to be localized in the nucleus of cells and notably expressed in the adrenal gland and testis. Other names for this target antigen include CFEOM2 and FEOM2. Indicated applications for Arix antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
