Extraction of #Inonotus #obliquus strains #Genomic DNA and Optimization of #RAPD System by Wang Shouming in BJSTR




Abstract

The strains of wild #Inonotus #obliquus were used as the materials. An improved #CTAB method of Inonotus obliquus DNA extraction was applied to obtaining genomic DNA. And it was used for template then to optimize #RAPD amplification conditions. The results indicated that: a volume of 25 μL was used which contained 40ng/μl template DNA, 10pmol primer, 2mmol/L Mg2+, 1.0 unit domestic Taq DNA #polymerase, 100μmol/L dNTP, others complement with ddH2O. The amplification program was that 1 cycle of 5 minutes at 94oC to initial #denature; 45 cycles of 1 minute at 94oC to denature, 1 minute at 40oC for annealing, 1.5 minutes at 72oC for extension; 5 minutes at 72oC for final extension.
