From: Decreased expression of C-erbB-2 and CXCR4 in breast cancer after primary chemotherapy
Western blot analysis: Expressions of C-erbB-2, CXCR4 and ER-a in breast cancer Fifty micrograms of total protein of tissue lysates from various breast cancer tissue were resolved on 4–15% SDS–PAGE and subjected to western blot analysis using antibodies that recognize phospho-specific C-erbB-2, CXCR4 and ER-a respectively. 1a-4b: 4 pairs of preoperative core biopsies and final surgical specimens. a: preoperative specimens; b: postoperative specimens.
