To identify an EBNA2 dependent cis-acting element , various TP1 promoter-reporter gene constructs were transfected in the absence and presence of an EBNA2 expression vector into the established B-cell line BL41-P3HR1 .
 ( protein: EBNA2, None) , ( cell line: B-cell line BL41-P3HR1, None) , ( DNA: EBNA2 dependent cis-acting element, None) , ( DNA: TP1 promoter-reporter gene constructs, None) , ( protein: EBNA2, None) , ( DNA: EBNA2 expression vector, None)
