Anti-EST-1 antibodies enable researchers to detect and measure the EST-1 antigen in biological samples. This target is a reported synonym of the SULT1E1 gene, which encodes sulfotransferase family 1E member 1. This protein is known to function in fat cell differentiation, among other biological roles. The human version of EST-1 has a canonical amino acid length of 294 residues and a protein mass of 35.1 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the liver, kidney, duodenum, colon, and appendix. Other names for this target antigen include EST and ST1E1. Indicated applications for EST-1 antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
