(Tos-GFHR)2-[Rh110] – Fluorescent Peptides

Candidate peptide substrate for kallikrein-related peptidase 5 (KLK5). In its intact state this peptide is not fluorescent, however when this substrate peptide is cleaved, Rhodamine 110 is released and thus fluorescence can then be detected. Contains rhodamine 110 group, a widely used red fluorescent tag. The terminal carboxylic acids in this peptide have been activated by the addition of the p-tosyl moiety, allowing for easy addition of functional groups or further peptide residues.
