[FITC]-Ahx-(KKEEE)3K carrier peptide – Fluorescent Peptides

The [FITC]-Ahx-(KKEEE)3K carrier peptide contains the fluorescent label fluorescein isothiocyanate (FITC), where the isothiocyanate can generate a stable thiourea linkage through reacting with the amine group present on protein molecules. The Ahx group (1,6-aminohexanoic acid) is used as a spacer to N-terminally link the FITC to the (KKEEE)3K carrier peptide. The (KKEEE)3K peptide sequence has shown significant specific renal targeting, thus giving it kidney-specific drug carrier properties. In particular its ability to target drugs to the proximal tubule cells of the kidney suggests potential to aid in the treatment of renal diseases.
