Protein expression of erbB2, P-erbB2, erbB3, P-erbB3 and AIB1 in breast tumor cell lines. The cell lysates from human breast cancer cell line SKBR-3 and the six novel, mammary tumor-derived cell lines were prepared as described in Materials and methods. 50 μg total cell lysates were used for Western blot analyses with antibodies directed against erbB2 (c-neu Ab-3, Oncogene Research Products), P-erbB2 (clone PN2A, NeoMarkers, Inc), erbB3 (Ab-7, NeoMarkers, Inc), P-erbB3 (clone 21D3, Cell Signaling Technology) and AIB1 (clone 34, BD Biosciences Pharmingen, San Diego, CA, USA).
