Genomic probes can be efficiently obtained for specific chromosomal regions by PCR amplification of gel slices containing fractionated restriction enzyme-cleaved DNA. Here, single-copy, human-specific DNA sequences were amplified using inter-Alu PCR on gel slices containing a NotI digest of DNA from hybrid cell line WAV17. Rodent cell line WAV17 contains human chromosome 21. About 75% of the 0.15- to 3-kb inter-Alu PCR products could be regionally assigned, en masse, by hybridization experiments using inter-Alu PCR probes generated from cell lines containing portions of chromosome 21. This work produced 10 new chromosome 21 markers that came from regions of 21q containing few useful markers. These markers were needed to finish a NotI restriction map for 21q. This approach provides markers needed to close map gaps and for top-down mapping approaches. 52 refs., 5 figs., 2 tabs.
