Our laboratory has developed a one-step quantitative reverse transcription polymerase chain reaction (RT-PCR) procedure in which the reverse transcriptase enzyme and Taq DNA polymerase are combined in the one tube and a single, non-interrupted, thermal cycling program is performed. In the past, RT-PCR has been carried out with two separate steps: (1) reverse transcription of RNA to generate a cDNA pool and (2) polymerase chain reaction amplification of the cDNA. The two-step method can affect the accuracy of the procedure as the total number of manipulations is greater, thereby allowing a greater chance for pipetting errors. Quantitation by our method is achieved in a single reaction by the use of a competitive internal standard that is identical in sequence to the target RNA except for a deletion of 107 base pairs and uses identical primers and cycling conditions. Using this method, we have been able to quantify the amount of message of a G protein (G), in small amounts of tissue, such as dorsal root ganglia, from embryonic as well as postnatal mice.
