S Tag Peptide acetate is a short oligopeptide derived from pancreatic ribonuclease A, encoded by pCITE-3 and -4 series vectors for in vitro translation and by pET-29 and -30 vectors for expression in E. coli. S Tag Peptide acetate is fused at the N-terminus of target proteins and contains a multiple cloning site region available in all three reading frames, enabling efficient protein expression, purification, and functional studies.
