New monoclonal antibody for tumor-associated protein PMEPA1 detection

We obtained a new monoclonal antibody (mAb) against tumor-associated protein PMEPA1 (Prostate Transmembrane Protein, Androgen Induced 1) for which is shown differential expression in some tumors. To test the specificity of obtained mAb we have produced a full-length recombinant PMEPA1 in transfected HEK293T cell line. After transfection of the plasmid vector pIRES-EGFP, containing the insertion coding PMEPA1 gene we evaluated PMEPA1 protein expression in HEK293T cells lines by immunocytochemical study and western-blot analysis. Ability of the new mAb binds PMEPA1 in clinical specimens is shown by immunohistochemistry on histological sections of prostate tissue used as positive control. New antibody may provide a basis for development of commercial antibody test for evaluation of protein expression in human biological samples.
