Anti-AREGB antibodies enable researchers to detect and measure the AREGB antigen in biological samples. This target is a reported synonym of the AREG gene, which encodes amphiregulin. This protein is known to function in cell to cell signaling and GPCR signaling pathways, among other biological roles. The human version of AREGB has a canonical amino acid length of 252 residues and a protein mass of 27.9 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the placenta. Other names for this target antigen include AR and CRDGF. A number of AREGB antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
