1SYBR greenⅠ实时荧光PCR方法检测GSTM1熔解曲线峰图
Realtime PCR assay with SYBR green I and melting curve analysis of GSTM1 gene. A: Differentiation of GSTM1, β-globin and negative controls by performing melting curve analysis; B: The present genotype of GSTM1 gene gives one peak with an average melting point of 86.0 ℃ (β-globin) and another with an average melting point of 82.2 ℃ (GSTM1); C: the null genotype of GSTM1 gene only gives a single melting point at 86.0 ℃ (β-globin).
