Figure 3. Pepsinogen protein was observed in pepsinogen mRNA-postivie BE specimens.

Figure 3

SDS-PAGE/Western blot was performed on 30ug lysate of biopsies from Barrett’s epithelium (B2, B9) and neighboring normal tissue (N2, N9) from patients whose BE specimens tested positive for pepsinogen mRNA. Pepsinogen protein was observed in BE specimens, whereas little to no pepsinogen was observed in neighboring normal tissue.
