Figure 1. Immunohistochemical staining of Toll-like receptor 3 (TLR3) expression in OE-E6/E7 cells. Positive staining is red and negative staining is blue. Small inserts show blocking of the anti-TLR3 antibodies with the corresponding specific peptide. (A) TLR3 gene expression was positive in this human fallopian tube cell line (OE-E6/E7; magnification, ×40). (B) The pair of TLR3 primers produced a specific product with the predicted size in the test T and control C samples.
