The polymerase chain reaction (PCR)-based method for screening pooled yeast artificial chromosome (YAC) libraries was modified by adding a step for the restriction enzyme digestion of the PCR products. This modification significantly increased the reliability of YAC screening and made it possible to identify YAC clones without a cumbersome verification step by colony hybridization and/or Southern blotting. Using this method, we assigned 39 mouse YAC clones to a mouse genetic map with 13 biallelic, polymorphic expressed sequence tags. This method provides a fast, reliable way to identify YAC clones with PCR-based sequenc-tagged sites.
