It was typical for the Jews of that time to have two names, one Hebrew, the other Latin or Greek. Jesus called him "Saul, Saul" in "the Hebrew tongue" in the book of Acts, when he had the vision which led to his conversion on the Road to Damascus. Later, in a vision to Ananias of Damascus, "the Lord" referred to him as "Saul, of Tarsus". When Ananias came to restore his sight, he called
S-tag S-tag S-tag is the name of an oligopeptide derived from pancreatic ribonuclease A (RNase A). If RNase A is digested with subtilisin, a single peptide bond is cleaved, but the resulting two products remain weakly bound to each other and the protein, called ribonuclease S, remains active although each of the two products alone shows no enzymatic activity. The N-terminus of the original RNase A, also called S-peptide, consists of 20 amino acid residues, of which only the first 15 are required for ribonuclease activity. This 15 amino acids long peptide is called S15 or S-tag. The amino acid sequence
