RESUMO

We have developed a simple two-dimensional YAC pooling strategy to facilitate YAC library screening via STS and Alu-PCR approaches. The method has been implemented using the human total genomic YAC library of Olson and coworkers, and its validity tested by isolation of many chromosomes 19- and 21-specific YACs. The Alu-PCR approach is notable in that it is hybridization-based, such that PCR primer pairs do not need to be repeatedly synthesized and tested for each screening step.
