The presence of the MLL-EB1 and the reciprocal EB1-MLL fusion transcripts was verified by reverse-transcription PCR.     ///    The genomic break junctions of MLL-EB1 and EB1-MLL were amplified by long-distance PCR.     ///    Immunofluorescence staining demonstrated that the MLL-EB1 fusion proteins were localized in the nuclei..
