Extracting RNA from pancreatic tissue is notoriously challenging because of the organ's high RNase content. Standard methods using TriPure or TRIzol classically yield RNA of sufficient quality for routine gene expression analysis but not for microarray or deep sequencing analysis. Here we developed a simple method to extract high-quality RNA from mouse pancreas. Our method uses an RNase inhibitor and combines different protocols using guanidium thiocyanate-phenol extraction. It enables reproducible isolation of RNA with an RNA integrity number around 9.
