although the presence of idxe and tip dependence is correlated in primary responses , studies of idiotype expression on mab and on plaque-forming cells ( pfc ) using mixed erythrocyte monolayers clearly show that at the single-cell level the properties are separable , i.e. , not all tip-recognizing pfc display idxe and a sizable proportion of cells producing non-tip-dependent antibodies are idxe+ .
