Should I spray RNAseZAP on my bench and pipettes before working with RNA? I am regularly using RNase at my bench and would like to work with RNA as well. Could traces of RNase on my equipment degrade my RNA?
The common practice in my lab is to work in a laminar flow cabinet and clean it with alcohol, then spray it with the RNAseZAP. I've always heard from my professors that, while DNAses are more uncommon, "RNAses are everywhere". So, zap it early, zap it all.
