Anti-SAT2 antibodies are used in the immunodetection of the protein spermidine/spermine N1-acetyltransferase family member 2. In humans, the canonical protein has a reported length of 170 amino acid residues and a mass of 19.2 kDa. Its subcellular localization is in the cytoplasm. It is widely expressed across many tissue types. A member of the Acetyltransferase protein family, SAT2 is known to catalyze the N-acetylation of the amino acid thialysine (S-(2-aminoethyl)-L-cysteine), a L-lysine analog with the 4-methylene group substituted with a sulfur. Synonyms for this target antigen include diamine N-acetyltransferase 2, diamine acetyltransferase 2, polyamine N-acetyltransferase 2, spermidine/spermine N(1)-acetyltransferase 2, and thialysine N-epsilon-acetyltransferase. SAT2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some SAT2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
