PLANT DNA EXTRACTION PROTOCOL

INTRODUCTION


For high-quality extractions of DNA, plant materials are among the toughest. The key is to make the tissues suitable for removal. Overall, the fluid nitrogen streak freezes, and the solidified tissue is subsequently crushed by a mortar and pestle. Liquid nitrogen is difficult to handle and in open conditions such as a studies hall, it is dangerous. Therefore we have adapted to the use of new tissue an incredibly simple plant DNA extraction convention. We have used fabric arranged in advance by drying. Here are the conventions and performance.


Protocol of extraction


1. Weight 0.3 g of tissue of the plant


2. Spot fabric on a fine slide glass. Hit the tissue in glue with an incredibly sharp single rim.


3. Transfer tissue quickly to the narrow tube of a 1.5 ml axis () and (discretionary) to the further cylindrical crush tissue





4. Provide 300 μL EBA, 900μl EBB and 100 μl SDS when the example has been ready.


5. 65o C for 10 min. vortex and brood.


6. Ice spot tube and 410 μL of acetic acid derivatives are included. Blend back on the ice for 3 min by turning and spot tube.


7. 13.200 rpm rotator for 15 minutes. (Use a cooled smaller rotator at 4o C when this is not conceivable) (


8. Stir 1 mL of supernatant into a miniaturised 1,5 mL tube scale, cover 540 μL of super-cold supreme isopropanol, and slip into ice over a 20 minute period.




9. 10,200 rpm rotator for 10 minutes. Supernatant dispossess. Wash and drain the pellet once and for five hundred μL 70% of ethanol


10. Suspend 600 μL TE from dry pellet. Include 60 μL of 3M (pH 5.2) and 360 μL of ultra cold outright isopropanol derivative sodium acetic acid. Twenty min on ice.


11. Steps 9−11 rehash twice.


12. Resuspend the agarose gel of the pellets in 50 μL TE
