Figure 6From: Rhinosinusitis derived Staphylococcal enterotoxin B possibly associates with pathogenesis of ulcerative colitisRT-PCR results of S. aureus DNA amplification. DNA templates were extracted from the surgical removed sinus tissue of the patients with UC-CRS. Lane 1 is negative control by adding water instead of DNA template. Lanes 2–11 are representative PCR bands of S. aureus DNA amplification.Back to article page
