Generation and Characterization of a Large Insert Chromosome 2 PAC Library

As one part of the National Laboratory Gene Library Project we are generating large insert, ~50 kb to ~250 kb, bacterial clone libraries using the pCYPAC cloning vector developed at Livermore . For a chromosome 2-specific PAC library, PAC clones are being generated from the hybrid cell line GM10826. DNA partially digested with MboI is size fractionated using PFGE and the DNA cloned into the BamHI cloning site of the pCYPAC-2 vector. As with the bacteriophage P1 cloning system, sucrose is being used to select for recombinants. Ligation mixes containing clones over 80 kb average size are being plated and the chromosome 2 clones identified by colony hybridization using both human and hamster probes. To date, approximately 2,500 chromosome 2 clones, ~1X chromosome 2 coverage, has been arrayed into microliter plates and we are continuing to array additional clones. The chromosome 2 representation of the library is being tested by PCR screening using STS primers distributed across the chromosome. Combining the chromosome 2 specific PAC library with the cosmid and fosmid library being generated here by the Gene Library Project (see abstract by Garnes et al.) in conjunction with STSs being developed here (see abstract by Gingrich et al.), and elsewhere, will allow for the construction of a high quality, high resolution physical map of chromosome 2.
