0引言肿瘤细胞对药物产生多药耐药性（MDR）是导致化疗失败的重要原因卜，“，我们观察了白血病患者骨髓或外周血单个核细胞中mdr基因（mdrl）和MDR相关蛋白（MRP）的基因表达情况，并对临床检测结果作了分析．1方法1．l试剂AMV逆转录酶、TaqDNA聚合酶，原平生物技术公司购人．
0 Introduction The multidrug resistance (MDR) of tumor cells is an important cause of chemotherapy failure. "We have observed mdr genes (mdrl) and MDR-related proteins (MRP) in bone marrow or peripheral blood mononuclear cells of leukemia patients. ) Gene expression and analysis of clinical test results.1 Methods 1. A reagent AMV reverse transcriptase, Taq DNA polymerase, Yuanping biotechnology company purchase.
