Binding signals of representative HerboChips probed by VEGF. The images were visualized by Cy5-labeled streptavidin after the binding of VEGF to A MFC-, B MY- and C GF-HerboChips, which were fabricated with extracts from Murrayae Folium et Cacumen, Myrrha and Ginkgo Folium, respectively. These HerboChips chosen to represent different binding signal strengths from weak (+), moderate (++), and strong (+++); as marked in Table 1
