In this report, we show that following incubation of L540 cells ( Hodgkin's disease -derived, T cell-like, CD30 + cells ) with the agonistic anti- CD30 monoclonal antibodies ( mAb ) M44 and M67 , two nuclear factor (NF)-kappa B DNA binding activities were induced in nuclear extracts , as determined in gel retardation assays .
 cell line: Hodgkin's disease -derived, T cell-like, CD30 + cells; protein: nuclear factor (NF)-kappa B; protein: M44; cell line: L540 cells; protein: M67; protein: mAb; protein: agonistic anti- CD30 monoclonal antibodies; protein: CD30; protein: CD30
