I am attempting to perform rep-PCR on gram-negative enteric bacteria for 
molecular subtyping purposes (Versalovic, method I am using to 
liberate the DNA from whole cells is to do freeze/thaw cycles. Can anyone 
tell me specifics on how to do this crude DNA extraction, such as how 
many cycles are usual needed and how long to boil/freeze the samples.
