RT-PCR analyses of hCx59 and hCx62 RNAs in different tissues of the human eye. Both the hCx62-specific primer combination USP2 - DSP2 (within the first exon) and the primer combination USP2 - DSP3 (intron spanning) yielded amplicons of about 1.3 kb and 1.1 kb, respectively, only with cDNA from retina. The intron-spanning primer combination USP2-DSP4 even failed to yield a signal with retina cDNA. The amplicon of 550 bp implies that hCx59 seemed to be expressed in retina and also very faintly in lens.
