these data indicate that the costimulation assay with anti-mu antibody explores the reactivity of normal human b cells to both bcgf and il-2 , whereas the preactivation assay with sac bacteria , due to a shorter reactivity to bcgf of activated human b cells , essentially represents a probe for the study of il-2-promoted b-cell proliferation .
