{"product_id":"m16675","title":"S Tag Peptide","description":"\u003cp style=\"padding-left:1em;\"\u003eS 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, it is 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. It is believed that the peptide with its abundance of charged and polar residues could improve solubility of proteins it is attached to. Moreover, the peptide alone is thought not to fold into a distinct structure. On DNA-level the S-tag can be attached to the N- or C-terminus of any protein. After gene expression, such a tagged protein can be detected by commercially available antibodies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct information\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 1748.91\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormula:\u003c\/strong\u003e C73H117N23O25S\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eChemical Name:\u003c\/strong\u003e 4-[(1-{[1-({1-[(1-{[5-amino-1-({1-[(1-{[4-carbamimidamido-1-({3-carbamoyl-1-[(1-{[1-({2-carboxy-1-[(1-carboxy-2-hydroxyethyl)carbamoyl]ethyl}carbamoyl)-3-(methylsulfanyl)propyl]carbamoyl}-2-(1H-imidazol-5-yl)ethyl)carbamoyl]propyl}carbamoyl)butyl]carbamoyl}-3-carboxypropyl)carbamoyl]-2-phenylethyl}carbamoyl)pentyl]carbamoyl}ethyl)carbamoyl]ethyl}carbamoyl)ethyl]carbamoyl}-2-hydroxypropyl)carbamoyl]-4-(2,6-diaminohexanamido)butanoic acid\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSmiles:\u003c\/strong\u003e CC(O)C(NC(=O)C(CCC(O)=O)NC(=O)C(N)CCCCN)C(=O)NC(C)C(=O)NC(C)C(=O)NC(C)C(=O)NC(CCCCN)C(=O)NC(CC1C=CC=CC=1)C(=O)NC(CCC(O)=O)C(=O)NC(CCCNC(N)=N)C(=O)NC(CCC(N)=O)C(=O)NC(CC1=CN=CN1)C(=O)NC(CCSC)C(=O)NC(CC(O)=O)C(=O)NC(CO)C(O)=O\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChiKey:\u003c\/strong\u003e SIOLHBFVZMHKPF-UHFFFAOYSA-N\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChi:\u003c\/strong\u003e InChI=1S\/C73H117N23O25S\/c1-36(83-59(107)37(2)85-71(119)57(39(4)98)96-67(115)47(21-24-55(102)103)87-61(109)42(76)16-9-11-26-74)58(106)84-38(3)60(108)86-43(17-10-12-27-75)63(111)92-49(30-40-14-7-6-8-15-40)68(116)90-46(20-23-54(100)101)64(112)88-44(18-13-28-81-73(78)79)62(110)89-45(19-22-53(77)99)65(113)93-50(31-41-33-80-35-82-41)69(117)91-48(25-29-122-5)66(114)94-51(32-56(104)105)70(118)95-52(34-97)72(120)121\/h6-8,14-15,33,35-39,42-52,57,97-98H,9-13,16-32,34,74-76H2,1-5H3,(H2,77,99)(H,80,82)(H,83,107)(H,84,106)(H,85,119)(H,86,108)(H,87,109)(H,88,112)(H,89,110)(H,90,116)(H,91,117)(H,92,111)(H,93,113)(H,94,114)(H,95,118)(H,96,115)(H,100,101)(H,102,103)(H,104,105)(H,120,121)(H4,78,79,81)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAppearance:\u003c\/strong\u003e Solid Power\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥98% (or refer to the Certificate of Analysis)\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShipping Condition:\u003c\/strong\u003e Shipped under ambient temperature as non-hazardous chemical or refer to Certificate of Analysis\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStorage Condition:\u003c\/strong\u003e Dry, dark and -20 \u003csup\u003eo\u003c\/sup\u003eC for 1 year or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShelf Life:\u003c\/strong\u003e ≥12 months if stored properly.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStock Solution Storage:\u003c\/strong\u003e 0 - 4 \u003csup\u003eo\u003c\/sup\u003eC for 1 month or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eDrug Formulation:\u003c\/strong\u003e To be determined\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHS Tariff Code:\u003c\/strong\u003e 382200\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProducts are for research use only.
