It is not clear whether structures of glucoprotein tumor markers such carcinoembryonic antigen (CEA) and CA19-9 differ or not in various cancers. Western blot analysis of the expression patterns in various cancers was performed using original antibody against CEA which we made. The expression pattern of them was ladder bands pattern. In serum from lung, bands larger than 150kD were observed, but they were not in serum form other cancer patients and normal control (p=0.0352). Expression patterns were evaluated in such analysis using antibody against CA19-9 in sera from pancreas and colon cancers. A clue of simple differentiation diagnostic method of glucoprotein tumor markers by the pattern analysis in Western blotting was established.

目前尚不清楚癌胚抗原 (CEA) 和 CA19-9 等糖蛋白肿瘤标志物的结构在各种癌症中是否存在差异。使用我们制备的针对 CEA 的原始抗体对各种癌症中的表达模式进行蛋白质印迹分析。他们的表达模式是阶梯带模式。在来自肺部的血清中，观察到大于150kD的条带，但在其他癌症患者和正常对照的血清中没有观察到这些条带(p=0.0352)。在这种分析中，使用来自胰腺癌和结肠癌的血清中针对 CA19-9 的抗体来评估表达模式。建立了一条基于Western blotting模式分析的糖蛋白肿瘤标志物简单鉴别诊断方法的线索。
