3’-UTR

  1. Column 1 represents primer combinations, column 2 – DNA fragment size after RT-PCR. Some of the primer combinations could give rise to two different DNA fragments from two different splice variants. Column 3 shows transcript variants predicted to be recognized by the respective primer combination. Column 4 demonstrates exon-to-exon splicing junction which were experimentally confirmed by RT-PCR using respective primer combination. ^ - transcripts detected by RT-PCR. * - primer combination which gave negative result in RT-PCR. Numbers in parenthesis refer to T3 promoter extension, as required for ISH probe generation (Table should appear after “Clcc1 transcripts detected in the retina” section in “Results”)
