应用Southern杂交、PCR和RT／PCR片段测序、合成寡核音酸探针、斑点杂交等分子生物学技术，对65例儿童急性淋巴细胞白血病进行抗原受体基因（TCRy、TCRS和IgH）重排和肿瘤融合基因（SIL－TAI，－l，BCR－ABL，AF4／HRX，AFg／HRX和HRX／ENL）转录本的研究。Ig和TCR基因的重排结
TCRy, TCRS and IgH rearrangements were performed in 65 children with acute lymphoblastic leukemia using Southern hybridization, sequencing by PCR and RT / PCR, synthesis of oligonucleic acid probes, dot blot hybridization and other molecular biological techniques And tumor fusion genes (SIL-TAI, -l, BCR-ABL, AF4 / HRX, AFg / HRX and HRX / ENL) transcripts. Rearrangement of Ig and TCR genes
