Immunoblot analysis of tissue extracts from breast cancers and normal tissues using 4C8MS and 4F10TT. Four samples of cancer tissues and normal counterparts collected from four cases of mastectomies were examined. When the extracts were analyzed with 4F10TT, bands at 350 (L), 250 (arrowhead) and 210 kd (S) were intensely labeled in breast cancers, but only weakly in normal tissues (left). With 4C8MS, 350 and 250 kd bands are apparently limited to breast cancers (right).
