Protocol for PCR straight from yeast colony?

John - I tried this protocol for the first time yesterday to prepare yeast
genomic DNA for PCR - it was fast and easy and worked.  Resuspend a yeast
colony (I used a large one) in 60 µL of lysis buffer, incubate at 37C for
60min, then boil for 10min.  Spin for 2 min in microfuge, then use 1µL of
the supernatant in a 10µL PCR reaction. 

Lysis buffer: 1U/µL lyticase, 0.45% (v/v)tween-20, 0.45% (v/v)NP-40, 50mM
KCl, 10mM tris pH 8.3, 1.5mM MgCl, 0.01% (w/v) gelatin.
