[Price Inquiry]
CAT#
GR1211
Sequence
Cys(Npys)-Tyr-Gly-Arg-Lys-Lys-Arg-Arg-Gln-Arg-Arg-Arg-NH2
M.W/Mr.
1816.1
Description
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.
Storage
-20°C
Solubility
Soluble in water for a solution up to 3 mg/ml, otherwise acetonitrile is recommend. Avoid repeated freezing and thawing.
