摘要 目的观察保存温度和时间对静脉血分离外周血单个核细胞(PBMC)存活率的影响。方法采集3名健康志愿者的肘静脉血液各20 mL,分为两管各10 mL后于4℃和25℃保存,分别于采血后2、6、12、24、48 h分离PBMC,行台盼蓝染色,光学显微镜下计数细胞存活率(重复3次取平均值)。结果随时间延长,4℃保存条件下分离的PBMC存活率无明显下降趋势,且均维持在85%以上,各时间点比较无显著差异(P>0.05);25℃保存者PBMC存活率呈下降趋势,但24 h内均保持在85%以上,仅48 h时存活率下降显著(P<0.05)。结论静脉血在4℃或25℃保存条件下,24 h内进行PBMC分离提取均可获得较高存活率;而4℃保存者可酌情延长至48 h内。
