<prompt> The following is a B cell specific mitogen:Concanavalin A conALipopolysaccharide LPSPokeweed mitogen PWMPhytohaemagglutinin PHA  <response>: Mitogens: Molecules that promote cellular mitosis in a non-specific way are known as mitogens. They activate lymphocytes but bypass antigen receptor specificity. Concanavalin A conA, Phytohaemagglutinin PHA and wheat gram agglutinin WGA promote human T cell proliferation. Lipopolysaccharide LPS is specific for B cell, while Pokeweed mitogen PWM promotes both T cell and B cell. Ref: Analytical Techniques, edited by T.P. Mommsen, Peter W.
