Fig. 1From: The effects of trastuzumab on HER2-mediated cell signaling in CHO cells expressing human HER2The expression of HER receptors in CHO cells stably transfected with a single HER receptor including CHO-EGFR, CHO-K6, and CHO-HER3. a Immunoblotting. The lysates of various CHO cells were separated by gel electrophoresis and immunoblotted with antibodies to HER receptors as indicated. The parent CHO cells (CHO) were used as control. b Immunofluorescence. Various CHO cells were fixed and stained with antibodies to HER receptors as indicated. The expression of HER receptor was revealed by FITC-conjugated secondary antibody (Green). Cell nuclei were counterstained with DAPI. Size bar: 10 μmBack to article page
