Fig 13. Western blot analysis of salivary toll like receptor 4 (TLR4) of individual saliva samples from dogs with benign oral tumors (BN), early- and late-stage oral melanoma (EOM and LOM, respectively), oral squamous cell carcinoma (OSCC) and periodontitis and normal controls (CP).

Representative western blot for TLR4 at 95 kDa (A) and bar graph of ratios of TLR4 protein intensity to total blotted proteins in each lane in the first half of a membrane* (B). a–b, c-d and c-e denote a significant difference at p<0.05, p<0.01 and p<0.001, respectively.
