Anti-xCT antibodies enable researchers to detect and measure the xCT antigen in biological samples. This target is a reported synonym of the SLC7A11 gene, which encodes solute carrier family 7 member 11. This protein is known to function in the response to oxidative stress, among other biological roles. The human version of xCT has a canonical amino acid length of 501 residues and a protein mass of 55.4 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include CCBR1 and cystine/glutamate transporter.
