Figure 1

AQP1 transcript and membrane expression levels were higher in HT29 cells than SW480 cells. (A) AQP1 mRNA levels in HT29 cells (n = 11) and SW480 cells (n = 10), as determined by qRT-PCR. (B) Ratios of signal intensity (anti-AQP1 to membrane dye), in HT29 and SW480 cells showing relative levels of membrane AQP1 expression. See methods for statistical analysis details.
