A number of ELISA Kits are available that target ST2, an alias of the protein, sulfotransferase family 2A member 1. The human protein, encoded by the gene SULT2A1, is a member of the Sulfotransferase 1 family. The protein's cellular localization is indicated to be cytoplasmic. Additional synonyms or past names for this protein may include: DHEA-ST, DHEAS, HST, ST2, ST2A1, ST2A3, STD, hSTa. Homology is conserved in other species, such as Mouse, Rat, Frog.
