Fig. 10From: Probing the subcutaneous absorption of a PEGylated FUD peptide nanomedicine via in vivo fluorescence imagingPosterior and lateral views of mice show increased and earlier FUD and PEG-FUD signal in the kidney region for lower MW peptides. A single dose containing a peptide and its sulfo-Cy5 conjugate counterpart was injected s.c. between the shoulder blades of a mouse. Arrows indicate apparent maximal peptide kidney signalBack to article page
