An effective elimination of false positives isolated from differential display of mRNAs.
A reverse Northern analysis that effectively eliminates the false positives isolated from differential display of mRNAs (DD) is demonstrated. Preparation of probe by one-step labeling in reverse transcription reaction is found to be more effective and specific as compared to the preparation of probe by random priming of reverse transcribed cDNA pool. Reverse Northern assay of DNA fragments isolated from DD prior to their cloning into plasmid, analysis of multiple fragments on single slot blot, and requirement of RNA only in small amounts as compared to conventional Northern makes the protocol quick, effective, and economic.
