Anti-gp91phox antibodies enable researchers to detect and measure the gp91phox antigen in biological samples. This target is a reported synonym of the CYBB gene, which encodes cytochrome b-245 beta chain. This protein is known to function in inflammatory response pathways and innate immune responses, among other biological roles. The human version of gp91phox has a canonical amino acid length of 570 residues and a protein mass of 65.3 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the rectum, lung, endometrium, colon, and bone marrow. Other names for this target antigen include AMCBX2, CGD, and CGDX. Western Blot is the most common application for the gp91phox antibodies listed below. ELISA and Immunohistochemistry are also common applications.
