Properties Suppliers
Cys(Npys)-(Arg)9 LAB GRADE 97%

This is a peptide comprising of 9 Arginine residues and is synthesized with an activated cysteine residue C(Npys), wherein Npys is 3-Nitro-2-pyridinesulfenyl group protects cysteine..The S(Npys) group of this cysteine-containing 9R is capable of reacting selectively with the free thiol group of another cysteine-containing peptide to form an unsymmetrical disulfide bond. Coupling of sulfhydrils has been studied as an effective means to deliver/release therapeutics such as siRNA in the reducing environment within the cell.More information please visit the website: http://www.creative-peptides.com/product/cys-npys-arg-item-gr1107-32474.html

Cys(Npys)-TAT (47-57) LAB GRADE 97%

This peptide corresponds to the protein transduction domain of the TAT protein and is synthesized with an activated cysteine residue C(Npys), wherein Npys is 3-Nitro-2-pyridinesulfenyl group and is used for activating S of cysteine and for rapid reaction when a thiol group is introduced. This kind of modification has been used to render this peptide as a cell penetrating and carrier peptide applicable in conjugation studies. http://www.creative-peptides.com/product/cys-npys-tat-item-gr1211-32476.html
