Centrifuge the sample at 25,000rpm for 5 to 8 minutes and transfer the supernatant into another tube. You have to modify the protocol and preparation as per your need. You can read the details below. Results from six grams of leaf tissue finely ground using a mortar and pestle, then aliquoted (1 g) for each extraction. Its better to leave a trace of ethanol and water in the pellet (and have it dissolve easily), than to remove all moisture, and then have great difficulty dissolving the pellet. Plants bear secondary metabolites and a diversely rigid cell wall made up of polysaccharides like pectin, cellulose, chitin, etc. A fragment analyzer Qsep100, that uses a capillary gel electrophoresis system, allowed . suitable for the elimination of polysaccharides and polyphenolic compounds otherwise affecting Rapid isolation of high molecular weight plant DNA.
