If the antibodies recognize their epitope on the MHC then complement activation occurs and the cell will be osmotically lysed.Another technique of tissue typing, "mixed leukocyte reaction", is performed by culturing lymphocytes from the donor together with those from the recipient. It tests cell mediated response against the tumor cells.
