	We have been able to PCR directly from crude phae lysates.
We do so without any treatment  and generally just take one microliter
of the lysate directly into the PCR tube. I have noticed that this
works fairly well if you have a high copy number of your target
template in the lysate, versus say, the contents of a genomic library
whereupon we get a high background...which may be explained by the way
the library was created...ie partial Sau 3A digest or just an over
abundance of nonspecific products. Our information was derived from
