Optimization of Chinese fir SRAP-PCR system
摘要
Abstract
In order to optimize SRAP-PCR reaction system for Chinese fir,the orthogonal design L16(45) was considered with different concentrations of Mg2+, dNTPs, primer, Taq DNA polymerase and DNA template in SRAP-PCR reaction system for Chinese fir. The results of PCR were evaluated by visual and variance analysis,then the concentrations of Mg2+, dNTPs,primer were rectified with single-factor design. Finally,the results showed that the best reaction system was the combination in 20μL reaction solution,containing of Mg2+ 2.25 mmol/L,dNTPs 0.15 mmol/L,primer 0.4 μmol/L,Taq DNA polymerase1.5μmol/min and DNA template 60 ng,2μL10×PCR Buffer and ddH2 O to 20μL. The first optimal an-nealing temperature was 35℃,and the second step was 53 ℃. The optimized reaction system of Chinese fir described a-bove can get clear and stable bands.关键词
