DNA extraction is relatively easy from citrus woody than non-citrus plants. Grind 50 mg of plant samples into powder in liquid nitrogen using pre chilled mortar and pestle. Lysis: Tissue grinder and use detergent. In this study, we compared three different protocols of DNA extraction: NaCl (saline); phenol-chloroform and commercial kit (Promega)from three biological tissues of five individuals of Lutjanus purpureus under two methods of storage. We use this method for extracting genome sequencing quality (i.e. However, the use of a CTAB buffer will surely help in the majority of cases. compounds and other contaminants remain in the supernatant and can be washed away. Liquid nitrogen (if available) Centrifuge the sample at 10,000rpm for 2 minutes and take supernatant to another tube. Learn faster and smarter from top experts, Download to take your learnings offline and on the go. DNA precipitates, resembling a thread of translucent white snot, at the interface between the juice and alcohol.
