Figure 3. Fluorescence imaging of subcutaneous IGROV1 tumour-bearing mice, 10 min and 5 h after IV injection of the probes (dissolved in PBS 10 mm, pH 7.4, with 10 % DMSO, 10 % EtOH), at 10 nmol Cy5 per mouse. The images are acquired and presented with the same camera settings, with the fluorescence
Fluorescence tomography today appears as a complementary imaging modality for assessing molecular processes in small living animals. A new design of fluorescent activatable units for the imaging of cellular internalization of probes is proposed. Disulfide bridges are used as intracellular cleavable
## Abstract __In vivo__ optical imaging using fluorescently labeled selfβquenched monoclonal antibodies, activated through binding and internalization within target cells, results in excellent targetβtoβbackground ratios. We hypothesized that these molecular probes could be utilized to accurately r
