Despite this lower affinity, a trimer of the BAT box sequence was as efficiently transactivated by an Oct-2 expression vector as was a trimer of the octamer sequence in HeLa cells .
 ( DNA: BAT box sequence, None) , ( DNA: Oct-2 expression vector, None) , ( DNA: octamer sequence, None) , ( cell line: HeLa cells, None) , ( protein: Oct-2, None) , ( DNA: BAT box, None)
