Figure 5

Distribution of trastuzumab, T-SA1 and T-SA2 in vivo was displayed by bioluminescence imaging system. Both T-SA1 and T-SA2 could target tumor tissues specifically within 2 h post injection and the maximum fluorescence intensity on the area of tumor was observed at 12 h post injection. The tumor tissue areas were shown with the red arrows. The liver areas were shown with the blue arrows.
