Tuftsin derivatives of FITC, Tb-DOTA or Gd-DOTA as potential macrophage-specific imaging biomarkers

Fluorescein- and terbium-labelled tuftsin (Thr-Lys-Professional-Arg) and pentapeptide (Thr-Lys-Professional-Professional-Arg) have been synthesized and their properties have been evaluated in vitro by luminescence spectrometry and confocal microscopy
