Large-scale screening of yeast artificial chromosome libraries using PCR.

The construction of physical maps of the human genome using sequence-tagged site content mapping requires that thousands of PCR amplifications be performed. On this scale, measures to reduce cost and to increase throughput become serious considerations. We describe relatively simple measures developed in our laboratory that increase the rate at which these reactions can be performed in a cost-effective manner. These measures have been extensively tested in our laboratory and are readily applicable in other laboratories including those performing library screening on a more modest scale.
