Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) offers a robust method for the measurement of RNA levels for any gene within cells harvested at any point before or during cell culture. The key elements of RNA extraction followed by a two-step qRT-PCR method (reverse transcription and PCR) are described, followed by a brief section on analysis of the results. There are a number of excellent kits available commercially for much of this work, but it is essential to ensure that the quality and quantity of cDNA produced is adequate for the standard PCR or array to be used.
