Resolution of the NF-kappa B complex in gel shift analysis shows that the binding protein , mobilized in naive Mono Mac 6 cells , consists mainly of p50 -p65 heterodimers , while in tolerant cells , the p50 homodimer is predominant.
 ( protein: p50 homodimer, None) , ( protein: -p65, None) , ( cell line: tolerant cells, None) , ( protein: p50, None) , ( protein: NF-kappa B complex, None) , ( protein: NF-kappa B, None) , ( protein: p50 -p65 heterodimers, None) , ( protein: binding protein, None) , ( cell line: naive Mono Mac 6 cells, None) , ( protein: p50, None)
