Binding signals of representative herbochips probed by β-TNF-α. The images were visualized by Cy5-labeled streptavidin after the binding of β-TNF-α to (A) PTE-, (B) AKE-, (C) SCE-, and (D) GBE-herbochips, which were fabricated with extracts from Pueraria thromsonii, Amumon kravanh, Syzygium caryophyllaceum, and Garcinia bancans, respectively. These herbochips chosen to represent different binding signal strengths from negative (−), weak (+), moderate (++), and strong (+++); as marked in Table 1.
