Figure 2. Biliary phosphatidylcholine (PC) is a function of Abcb4 gene expression.
Bile was collected from age-matched mice that express the Abcb4 gene (wild-type, WT), heterozygous expression (+/−), and homozygous deletion (−/−). Biliary PC concentration was determined using a colorimetric assay. Data are expressed as the mean ± SD (n=3). **p<0.01 vs. WT.
