CYP7A1 in Human Hepatocytes. CYP7A1 was detected in immersion fixed human hepatocytes induced with dexamethasone for 48 hours using Mouse Anti-Human CYP7A1 Polyclonal Antibody (Catalog # MAB9120) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (green). Specific staining was localized to endoplasmic reticula and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

CYP7A1 (cytochrome P450 7A1; also Cholesterol 7-alph-monooxygenase) is a 504 aa oxidoreductase enzyme (SwissProt #: P22680). Human CYP7A1 shares 81% and 82% aa identity with mouse and rat CYP7A1, respectively. It is expressed in the liver where it catalyzes cholesterol metabolism, which is the rate-limiting step in bile acid synthesis. Disruption of CYP7A1 is associated with high plasma cholesterol levels leading to increased risk of coronary artery disease.
