In spite of its association with p50 in vitro , however , we found a lymphoid cell-specific nuclear factor in vivo that contains c-Rel but not p50 epitopes ; this factor , termed IL-6 kappa B binding factor II , appears to contain the c-Rel homodimer and preferentially recognizes several IL-6 kappa B-related kappa B motifs .
