Expression of Immunoglobulin M (IgM) in Multiple Epitheliogenic Malignant Tumor Tissue and Carcinoma Cell Lines

Objective To examine the expression level of immunoglobulin M (IgM) in multiple epitheliogenic malignant tumor tissue and carcinoma cell lines. Methods Tissue microarray and immunohistochemistry were utilized to detect the expression level of IgM in ten epitheliogenic malignant tumor tissue and control negative tissue. Furthermore, flow cytometry and indirected immunofluorescence were utilized to detect the IgM expression level in eight epithelial carcinoma cell lines and the Burkitt's lymphoma cell line (R...
