Analysis of gene expression profiling of normal retina and brain cortices

ABSTRACT: Using a canine custom retinal cDNA microarray our aim is to identify normal gene expression profiling for retina and frontal, occipital and temporal brain cortices Total RNA was isolated using Trizol reagent (Invitrogen, Carlsbad, CA) and further purified by Rneasy mini kit (Qiagen, Valencia, CA). Purity and RNA quality were evaluated by absorbance at 260 nm and by denaturing formaldehyde agarose gel electrophoresis. High quality RNAs with A260/280 ratio over 1.8 and intact 28S and 18S RNA bands were used for microarray analysis. To generate an RNA reference sample for microarray hybridizations, we pooled equal amounts of total RNA from the occipital, temporal, and frontal brain regions collected from three 16-week-old beagles to achieve a homogeneous pool of transcripts. The pooled RNA wa
