Serial sections of a cancer tissue specimen were prepared with a combination of monoclonal antibodies of different kinds-SHI (IgG_3), FH4(IgG_3), FH_6(IgM), AH_6(IgM), and TKH_2(IgM)-and stain ed with an immunohistochemical method(ABC kit) to examine stained areas. Staining properties of individual monoclonal antibodies were recognized as differences in stained areas, being indicative of mosaicism. This finding is considered one mode of expression of the heterogeneity of cancer.A positive result was obtained in 100% of the cancer tissue specimens when a combination of monoclonal antibodies was used. The technique by means of monoclonal antibodies has been thus found to be effective for the histological diagnosis of cancer. The suggestion has also been made that elucidating its heterogeneity aids in the selection of an appropriate anticancer drug.

使用不同种类的单克隆抗体（SHI（IgG_3）、FH4（IgG_3）、FH_6（IgM）、AH_6（IgM）和TKH_2（IgM））组合制备癌组织标本的连续切片，并用免疫组织化学方法（ABC试剂盒）检查染色区域。各个单克隆抗体的染色特性被认为是染色区域的差异，表明嵌合体。这一发现被认为是癌症异质性的一种表达方式。当使用单克隆抗体组合时，100%的癌症组织标本获得了阳性结果。因此，已经发现利用单克隆抗体的技术对于癌症的组织学诊断是有效的。还建议阐明其异质性有助于选择合适的抗癌药物。
