Expression of G protein subunits and other olfactory genes in the cornea.

<p>The RT-PCR analysis of corneal RNA was performed as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096435#pone-0096435-g001" target="_blank">Fig. 1</a> legend. For primers located within a single exon PCR was performed with (+) and without (–) the RT step. For primer pairs located in separate exons only results of PCR with (+) the RT are shown. Arrows indicate the positions of the predicted PCR fragment sizes for <i>Taar4</i> (140 bp), two splice variants of Gαolf (314 and 607 bp), <i>Gna15</i> (118 bp), <i>Reep5</i> (347 bp), <i>Rtp3</i> (180 bp), <i>Omp</i> (150 bp) and <i>Emx2</i> (133 bp). Molecular markers (M) are from a 100 bp DNA ladder; the lowest band is 100 bp.
