摘要: 目的 建立通用的ALDH2 基因PCR 反应体系,筛选出各反应因素的最佳水平。方法采用正交设计L16(45)在4 个水平5 个因素(Taq 酶、引物、Mg2+、dNTP 和模板DNA)对ALDH2 基因PCR 反应体系进行实验,两次结果分别用统计软件MINITAB 进行分析,利用梯度PCR 确定引物最佳退火温度。结果 ALDH2 基因PCR 反应的最佳反应条件为:为25 L 体系中包含:Mg2+(25 mM)2.5 L、dNTPs(2.5 mM)2.0 L、引物上游和引物下游各(2.5 M)3.0 L、模板DNA 3.0μL、10×PCR buffer 2.5 L、Taq 酶1.5U,退火温度为60℃。结论 这一通用PCR 反应条件的建立为实现ALDH2 基因多态性检测建立了基础。

Abstract: Objective To develop the most suitable PCR system for ALDH2. Methods The orthogonal design was used to optimize PCR reaction system for ALDH2 with five factors(Taq DNA polymerase, Mg2+, DNA template, dNTPs and primers) at four levels respectively. Results The most suitable PCR system for ALDH2 was established, namely 25 L reaction system containing 2.5 L Mg2+(25mM), 2.0 L dNTPs mix(2.5mM), 3.0 L primers(2.5mM), 3.0 L DNA (~30ng), 2.5 μL of 10×PCR buffer, 1.5U of Taq DNA polymerase. The optimal annealing temperature was 60 based on gradient PCR. Conclusion This universal system provideda standardizing program for the ALDH2 gene polymorphism.
