An in vitro binding site selection procedure was used to determine DNA sequences preferentially bound by wild-type HLF and chimeric E2A- HLF proteins isolated from various t(17;19)-bearing leukemias .
 ( protein: wild-type HLF, None) , ( protein: HLF, None) , ( protein: chimeric E2A- HLF, None) , ( cell line: t(17;19)-bearing leukemias, None) , ( protein: HLF, None) , ( protein: E2A- HLF, None)
