From: Caveolin-1 expression is elevated in claudin-low mammary tumor cells
(A) Western blot of Cav-1 protein in two epithelial murine mammary tumor cell lines (4T1 and RJ345) and two murine mammary claudin-low cell lines (RJ348 and RM11A). β-actin served as a loading control. Immunofluorescence of Cav-1 (green) in RJ345 (B), 4T1 (C), RJ348 (D) and RM11A (E). Blue fluorescence indicates cell nuclei staining positive for DAPI; scale bars, 50 μm
