Hi, Thanks very much to everyone who replied to my query about methods for extracting clean DNA from Vitis aestivalis. I am still working my way through the suggestions, but all the responses were very helpful. To see all the responses in Word format, go to: http://biology4.wustl.edu/olsen/KateWaselkov.htm and click on the link in the second paragraph. Thanks again, Kate Waselkov Ph.D. Student Washington University in St. Louis kewaselk@artsci.wustl.edu
