In whole blood culture, pokeweed mitogen (PWM) is unable to stimulate human lymphocytes. This is because the mitogenic property of PWM is inactivated by erythrocytes, presumably due to absorption. The inactivation was observed with as few as 5 × 106/ml of human erythrocytes. Therefore, when PWM is used to study the functions of human lymphocytes, especially of suppressor T lymphocytes, erythrocytes should be removed from lymphocyte preparations for accurate analysis.
