ERα staining of MCF7 and SKBr3 cells. Selective ERα staining demonstrated in MCF7 (ERα+) and SKBr3 (ERα) cells. From left to right: DAPI counterstain (fluorescent blue), cytokeratins 8, 18, and 19 (CK) stained with Phycoerythrin (red), estrogen receptor (ERα) stained with AlexaFluor 488 (green), and a composite of all channels. MCF7 showed positive nuclear staining in AlexaFluor 488 indicating positive ERα expression, while SKBr3 was negative.
