The last author is usually the Principal Investigator (PI), also known in graduate school parliance as 'the slave master' or, as in Disney's film "Fantasia", 'the Sorcerer'. Good!John CTue, 12 Aug 2008 14:18:02 -0000http://www.thinkgene.com/new-dna-based-assay-rapidly-identifies-e-coli/#comment-2464691Reagent costs themselves should be more than a few dollars. The hard part is going to be keeping the reagents cold/frozen in villages without electricity. I read about an invention a few months ago about a device that you heated and it cooled things for several hours. But many other techniques exist, such as <a href="http://www.newmediaexplorer.org/chris/2004/04/14/cool_fridge_without_using_electricity.htm" rel="nofollow">http://www.newmediaexplorer.org/chris/2004/04/1...</a><br><br>We did an experiment with those chemical hand warmers you guy at Wal-mart or any other store, and stuck a tube in them. It was the perfect temperature for the reaction, and an hour later we got a positive result. <br><br>So in short, this should be very cheap and practical in developing countries.Josh HillSat, 09 Aug 2008 23:53:30 -0000http://www.thinkgene.com/new-dna-based-assay-rapidly-identifies-e-coli/#comment-2464688Great. How much do you think would you test cost in a developing country when commercialized ?Nikhil ChopraSat, 09 Aug 2008 23:46:05 -0000http://www.thinkgene.com/new-dna-based-assay-rapidly-identifies-e-coli/#comment-2464690Congratulations!drewyatesFri, 08 Aug 2008 00:16:34 -0000
