From: Cloning and expression of the rabbit prostaglandin EP2 receptor
RNase protection assay demonstrating the distribution of EP2 and GAPDH mRNA in normal rabbit tissues. The protected fragments were electrophoretically separated on a 6% agarose/7 M urea gel. The film was exposed for 36 hours. A 100 bp ladder was used as a size marker. Densitometry was used to quantitate EP2 mRNA expression, RNA loading was corrected by normalizing to GAPDH mRNA expression.
