Hybridization of YACs 986_e_10 and 950_e_2#9 to a high-density filter of the gridded keratinocyte cDNA library. Autoradiographs show a quarter of a blot containing 18,432 double-spotted cDNA clones, which was successively hybridized with 32P-labeled DNA derived from YACs 986_e_10 and 950_e_2#9, respectively. Positive clones are detected by two spots arranged in a specific pattern. Clones identified with both YACs were subtracted. Arrows indicate examples of a subtracted clone (black arrows) and of potentially EDC-specific cDNAs (white arrows).
