Assessing Gene Expression of the Endocannabinoid System Components by Real-Time Quantitative Reverse Transcription Polymerase Chain Reaction

: Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR), a major development in PCR technology, is a powerful and sensitive gene analysis technique that has revolutionized the field of gene expression assays. In this chapter, we describe in detail RNA extraction, reverse transcription (RT), and relative quantification of genes forming the endocannabinoid system in different experimental models. In particular, we here provide specific and sensitive assays to be used to assess gene expression of the endocannabinoid system components in mouse, rat, or human samples.
