A monoclonal antibody (MoAb), MLuC1, derived from the fusion of P3-X63-Ag8-U1 mouse myeloma cells with spleen cells from an HR mouse immunized with the carcinoma cell line SW626, was studied to define its reactivity profile on normal and neoplastic human tissues and its potential clinical applications in lung cancer. Evaluation of paraffin sections using the ABC immunoperoxidase method showed a 'pan-epithelial' reactivity; a large majority of epithelial components of organs in the respiratory, digestive and urogenital systems (except liver, rectum and ovary) were immunostained. As regard to neoplastic tissues MLuC1 recognized 84% of lung carcinomas (82% of small cell, 100% of squamous cell, 74% of adenocarcinomas), 86% of breast and 62% of ovarian carcinomas. On the contrary, MLuC1 was non-reactive with the other normal and tumoral non-epithelial tissues. Due to its spectrum of reactivity this MoAb could be useful for different diagnostic purposes such as differential diagnosis and lung cancer cytology.
