Figure 5. Monitoring of fluorescence-probe-modified peptide Cy5.5-Lira released from PCGA-PEG-PCGA thermogel.

Figure 5

(a) The fluorescence of Cy5.5-Lira in ICR mice was monitored by non-invasive live imaging at different time points after SC injection. (b) Ex vivo organ distributions of degradation segments of Cy5.5-Lira at indicated days after SC injection. The livers, kidneys, lungs, spleens and hearts were isolated from mice at predetermined time points and fluorescence intensities were monitored. “D” denotes “day”.
