Cyp1a2 genotyping by PCR

This protocol uses Ampitaq Gold from Perkin-Elmer, which eliminates the need for a manual hot start.  The protocol will work just as well using the taq of your choice and a manual hot start. If you are not going to use Amplitaq Gold you will need to adjust the annealing temperature (higher). The protocol uses three oligos that will distinguish between +/+, +/-, and -/-.  The 0.9kb band is the -/-, the 1.2kb band is the +/+, and both the 0.9kb and 1.2kb bands are the +/-.  To get the best results read your sample on a spectrophotometer and then dilute your sample to 100ng/ul.
