Figure 1. Electrophoretic analysis of conventional AQP5 reverse-transcription polymerase chain reaction in keratoconus and non-keratoconus corneal tissue. Amplicons for AQP5 were visualized in a 1.5% agarose ethidium bromide gel from both samples KC and non-KC corneal tissue. Lane 2, corresponds to AQP5 amplicon from KC corneal tissue; lane 3, corresponds to AQP5 amplicon from non- KC corneal tissue. Molecular weight markers are shown in lane 1. Similar bands intensities are observed.
