The following is true of mitogens mitogens Mitogens that selectively activate B cells will cause polyclonal stimulation of B cells. Non-specific stimuli, do not act through the antigen-specific receptor Lectins, including concanavalin A (Con A) and phytohemagglutinin (PHA), are very effective T-cell mitogens. Pokeweed mitogen (PWM) is a lectin with potent mitogenic properties PWM stimulates polyclonal activation of both B and T cells. Concanavalin A and phytohemagglutinin, are very effective B-cell mitogens
T-cell assays are Cytotoxicity assays measures the activity of CD4 +T cells against radiolabeled cells Assays that measure T helper cell function focus on helper activity for B cells can be used to measure the helper properties of CD4+T cells Cytotoxicity assays measures the activity of CD8+ cytotoxic T cells against radiolabeled cells Antibody-dependent cell-mediated cytotoxicity is studied by culturing radiolabeled cells with NK cells and cell-specific antibodies
