MOESM4 of Probing the subcutaneous absorption of a PEGylated FUD peptide nanomedicine via in vivo fluorescence imaging

Additional file 4: Fig. S4. In vivo fluorescence imaging of mFUD and 10-40 kDa PEG-mFUD remaining dose after s.c. administration of a solution containing the peptide and its sulfo-Cy5 conjugate between the shoulder blades of the mouse. A blue circle drawn between the shoulder blades of each animal indicates regions of interest (ROI) used to indicate the location of the dose to quantify the total remaining dose. Same scale (8.75x107-1.57x1010) is used to visualize the fluorescence intensity in all images.
