From: Decreased NPC1L1 expression in the liver from Chinese female gallstone patients
Presence of hepatic NPC1L1 in female gallstone patients (GS) and female gallstone-free patients (GSF). Tissues were immunohistochemically stained for NPC1L1 (A, B). Hepatic specimens shown are from female GS (A) and female GSF (B). Panel C shows results in the absence of primary antibody for NPC1L1. Panels A, B are superimposed with optical density results (red colour) derived from ImageJ. All samples were counterstained with haematoxylin; original magnification 10× (A, B) and 40× (C).
