TAT (47-57) GGG-Cys(Npys)
This peptide corresponds to the protein transduction domain of the TAT protein and is synthesized from activated cysteine residue C (Npys), where Npys is 3-nitro-2-pyridinesulfonyl, used to activate the S of cysteine And the rapid reaction when introducing sulfhydryl groups. For applications that require certain coupling reactions with the free N-terminus, make the N-terminus free, place the linker GGG at the C-terminus, and synthesize the peptide with the C (Npys) group. This modification makes it a cell-penetrating and carrier peptide that can be used in binding studies.
