Real-time PCR has become a robust and a routine approach for detecting and quantifying nucleic acids. Thus, real-time PCR is used for measuring the expression of genes, validating the results from micro-array experiments, genotyping, analyzing DNA variations (such as DNA SNPs) as well as for monitoring various bio markers in microbiology and oncology.
In this lab course we will discuss the fundamentals of real-time PCR and will review many of its applications. The participants will have an opportunity to practice quantification of gene expression. We will conduct experiments with samples containing low copy number of the target DNA by preforming pre-amplification to overcome such a common limitation. Towards this end, we will prepare RNA for mRNA expression analysis and RNA for micro-RNA (miR) expression analysis. Subsequently, two classes of chemistries will be introduced. The first utilizes the dsDNA binding fluorescent probe SYBR and the other technology utilizes a target-specific probe that fluoresces upon hybridization and hydrolysis (TaqMan). Most importantly, we will practice two methods for data analysis (the standard curve-assited mode of analysis and the DDC method). We will demonstrate primer design, and we will discuss and practice strategies for data analysis and statistical evaluation of the data. Finally, we will discuss various aspects of experimental design and requirements of adequate report of results according to the recently established MIQE guidelines.
