Using Wp reporter constructs in in vitro transfection assays , we found that Wp was 11- to 190-fold more active in B cell than in non-B cell lines and that three regions of the promoter (termed UAS1 , UAS2 , and UAS3 ) contributed to transcriptional activation .
 ( DNA: UAS1, None) , ( cell line: B cell, None) , ( cell line: non-B cell lines, None) , ( DNA: promoter, None) , ( DNA: Wp reporter constructs, None) , ( DNA: UAS3, None) , ( DNA: UAS2, None)
