Sample differential hybridization results. Duplicate filters with an array of 63 unknown clones from a human retina cDNA library in λgt10 were probed with human fibroblast cDNA (filter 3196) or 13GS retina cDNA (filter 3197). Clones that hybridized exclusively or preferentially to the 13GS retinal probe were selected for further investigation. Two examples of clones marked for further study, D4 and F8, are indicated by white asterisks.
