Fig. 2. Subcellular distribution of Ntcp in rat liver. Livers were perfused with Krebs-Henseleit buffer with or without GCDC (20 µmol/l) up to 90 min. Cryosections of livers were immunostained for Ntcp and Na⁺/K⁺-ATPase, and analysed by SR-SIM. Representative pictures of at least 3 independent experiments are given. The scale bars correspond to 10 µm in the overviews (upper row) and 1 µm in the four bottom rows with higher magnification of the plasma membrane.
