Product Name Cys(Npys) - (D - Arg)9
C(Npys)rrrrrrrrr - NH2
Size 1 mg
Catalog # AS-61206
US$ $291

This is a peptide comprising of 9 D-Arginine residues and is synthesized with an activated cysteine residue C(Npys), wherein Npys is 3-Nitro-2-pyridinesulfenyl group protects cysteine. This kind of modification has been used to render this peptide as a carrier peptide applicable in conjugation and cell permable studies. 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. In a bioconjugation study, D-Arg-C(Nyps) was shown to mediate delivery of TALEN proteins into mammalian cells.
