Immunohistology of the Antigenic Pattern of a Continuous Cell Line From a Human Colon Tumor

摘要: The antigenic surface pattern of a continuous cell line (HT29) derived from human primary carcinoma the colon was studied by immunofluorescence technique. Monovalent and polyvalent immune sera were used. cells this long-term culture kept ability to synthesize three principal tumor antigens: carcinoembryonic nonspecific cross-reacting antigens, membrane-associated tissular autoantigen. On HT29 cells, which still carry original blood group donor, no receptors for Ig's detected.
