In DNA pool sequencing to caculate the allele  frequence of a SNP, How many samples should I use and How can I make the DNA quality be equal?

Make sure all your DNA is equimolar by using a spectrophotomer then add the same ul amount of each for your pool. There is no fixed number that should be in your pool - less (ie 5) increases the odds of finding rare alleles while more allows you to scrren greater numbers of samples with the chances of missing a rarer allele here and there. See Wang et al Science 1998 280:1077-1082, Germer et al Genome Res 10:258-266, and Brouillette in Mam Gen Dec 2000.

Good luck.
