Tail DNA for PCR (No Organic Solvents)

1. Obtain the last 2mm of tail and place directly into 200ul 1X PCR Buffer
with Nonionic Detergents (PBND) in a 1.5ml microfuge tube. (Tails can be
stored at frozen in PBS or PBND until use.)

2. Add 1.2 ul ProK solution (I han't seen any problem with up to 5 ul ProK
and tail degredation is slightly faster) to each sample and place in a 55oc
bath.

3. Incubate at 55oc with occasional vortexing until tissue is degraded (1-3
hours).

4. Heat samples to 95oc for 10 min. in PCR machine or by boiling to
inactivate ProK.

5. Add 2ul(note)  processed Tail DNA / 50ul PCR reaction.
   note: this volume will vary depending on your particular PCR primers,
   their Tm etc....
