Abstract: | A simple, efficient and reliable CTAB method is standardized for genomic DNA isolation from fresh young leaves of a traditional medicinal plant Meyna spinosa. Key steps in the modified procedure include additional chloroform: isoamyl alcohol (24:1, v/v) extraction, addition of 4% PVP in the extraction buffer and an overnight isopropanol precipitation at room temperature. This procedure yields a high amount (46 μg DNA g?1 fresh leaf tissue) of good quality DNA free from contaminants. The isolated DNA is suitable for digestion with EcoRI and HindIII restriction enzymes and can be used in other DNA manipulation techniques. |
