IMPROVED LYSIS AND REVERSE TRANSCRIPTION FOR MRNA QUANTIFICATION

摘要

The present invention is directed to a method for performing an RT-PCR for amplifying a target RNA comprising the steps of a) lysis of a cellular sample which is supposed to contain the target RNA with a lysis buffer comprising between 0.2 M and 1 M guanidine thiocyanate, b) diluting the sample to an extend such that guanidine thiocyanate is present in a concentration of about 30 to 50 mM, c) reverse transcribing in the presence of a mixture of first strand cDNA synthesis primers, the mixture consisting of oligo dT primers and random primers, and d) subjecting the sample to multiple cycles of a thermocycling protocol and monitoring amplification of the first strand cDNA in real time.
