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; cell line: B-cell line BL41-P3HR1; DNA: EBNA2 dependent cis-acting element; DNA: TP1 promoter-reporter gene constructs; protein: EBNA2; DNA: EBNA2 expression vector
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
