found this nosing around Youtube. I am sure many of you long timers have probably already seen this but it was new to me and an excellent review. Wish I had found something like this when I was first dxd, would have saved me a headache or two figuring this out on my own. Anyway, here is the link and many thanks to the Canadian Leukemia Society, they sure supply us with some great information!
sorry, for some reason it did not set as a "clickable" link so you will either have to type it in or go to Youtube and do a search for PCR
Thanks for the catch Chris (in my defense, just got new glasses and still adjusting, hehehe
