    Dual Differential Roles of Cancerous Immunoglobulins as Suggested by Interactions with Human Serum Proteins
    Author(s): Gregory LeeGregory Lee

    In search of functional roles of immunoglobulins expressed by cancer cells, molecular interactions between cancerous immunoglobulins and human serum proteins or protein fragments were investigated by using RP215 monoclonal antibody as the unique probe. RP215 was initially generated against OC-3-VGH ovarian cancer cell extract and shown to react with carbohydrate-associated epitope located mainly on the variable regions of immunoglobulin heavy chains and others expressed by cancer cells which are designated in general as CA215. CA215 and cancerous immunoglobulins (cIgG) were affinity isolated from the shed medium of cultured cancer cells. Furthermore, by using purified CA215 and cIgG as the respective affinity ligands, the serum proteins or components were affinity isolated and subject to analysis by LCMS/MS methods. The results of such analysis suggest that as many as 80-86% of the is.. Read More»
