2.0 MATERIALS AND METHODS 2.1 Plant material and extract

A stock solution of plant aqueous extract was prepared by dissolving 100 mg of extract in 1 ml of sterile distilled water. Likewise, for the ethanol extract, 100 mg of extract was dissolved in 1 ml of 10 % Tween-20 rather than the original solvent (i.e. Dimethyl sulfoxide), and so the initial concentration of the plant extract (100 mg/ml)

Aug 18, 2018· These standards are electrophoresed with 300 ng-is of plant-extracted DNA. For example, the purity of extracted DNA is 33% if the band densities of 100-ng λ-DNA and plant extract are the same. Purities of plant DNA extract are usually less than 10% only with the popular treatments with PCI (later described), RNase, and ethanol precipitation.
