Immunoblots comparing UT-B abundance between ascending and descending colon protein, using surgical tissue samples and the BUTB-PAN antibody. A: immunoblot comparing expression between ascending and descending human colon of 1) glycosylated 35-kDa UT-B protein in plasma membrane-enriched samples and 2) unglycosylated 30-kDa UT-B protein in intracellular membrane-enriched samples. B: summary of the immunoblot densitometry results for UT-B abundance in ascending and descending human colon. Although there was a significant decrease in the levels of unglycosylated 30-kDa UT-B protein, the ascending colon actually contained significantly more glycosylated 35-kDa UT-B protein than the descending colon. *P < 0.05, **P < 0.01 vs. descending colon by ANOVA (n = 3).
