Anti-complement component 8 alpha subunit antibodies enable researchers to detect and measure the complement component 8 alpha subunit antigen in biological samples. This target is a reported synonym of the C8A gene, which encodes complement C8 alpha chain. This protein is known to function in immune response pathways, among other biological roles. The human version of complement component 8 alpha subunit has a canonical amino acid length of 584 residues and a protein mass of 65.2 kilodaltons. It is reported to be localized in the cell membrane and is secreted of cells. Other names for this target antigen include complement component C8 alpha chain and complement component 8 subunit alpha.
