Abstract:

目的 建立急性白血病(AL)患者八色流式免疫表型分析起始管方案。方法 用胞膜CD3(CD3)、CD19、CD10、CD34、CD45、胞浆CD79a(cCD79a)、髓过氧化物酶(MPO)和胞浆CD3(cCD3)等8种抗体建立八色流式染色方案。膜表面抗体直接染色;膜内抗体经固定破膜,再染色后上机检测。将3个血小板减少患者骨髓标本分别进行抗体的单色染色和缺一色染色;最后对17例确诊的AL初发患者标本进行检测。结果 用单色染色来确定染色方案中各抗体的检测电压及荧光补偿;缺一色染色中,阳性细胞群较单色染色变化均<10%,表明方案中的各抗体相互作用小。17例AL初发患者中,6例急性B淋巴细胞白血病原始细胞均为CD34和CD19阳性,5例cCD79a阳性和4例CD10阳性;4例急性T淋巴细胞白血病患者均为cCD3阳性;6例急性髓细胞白血病均为CD34和MPO阳性;1例B+T混合表型AL患者CD34、cCD3、CD19、cCD79a及CD10均为阳性,MPO和CD3为阴性,此检测方案能够确定各类AL的细胞类型。结论 建立了AL患者八色流式免疫表型分析起始管方案,操作简便快速,适用于临床检测。
