Anti-DHEAS antibodies enable researchers to detect and measure the DHEAS antigen in biological samples. This target is a reported synonym of the SULT2A1 gene, which encodes sulfotransferase family 2A member 1. This protein is known to function in cholesterol metabolism and homeostasis and the metabolism of lipids, among other biological roles. The human version of DHEAS has a canonical amino acid length of 285 residues and a protein mass of 33.8 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the stomach, small intestine, liver, duodenum, and adrenal gland. Other names for this target antigen include DHEA-ST and DHEA-ST8. A number of DHEAS antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
