Figure 3. Differential array screening. Clones in the C/r cDNA were spotted on two membranes at the identical positions, and they were hybridized with the cone (A) or the rod (B) cDNA. A pair of arrows or arrowheads indicates the candidate cDNA clone that is expressed preferentially in cones. As controls, plasmid vectors were spotted (small empty arrowheads).
