Identification of cDNAs by Direct Hybridization Using Cosmid Probes

The goal of this effort is to quickly obtain as many chromosome-specific cDNAs with as much map and sequence detail as possible. Many techniques have been proposed to isolate and identify genes within defined genomic regions; the technique discussed here is direct hybridization of a relatively complex genomic probe, an entire cosmid clone, to cDNA libraries. This method continues to be a straightforward technique with a fair number of successes.
