WebIn both cases, RNA is reverse transcribed into cDNA, and the cDNA is then used as the template for qPCR amplification. One-step and two-step refer to whether the RT and real-time PCR amplification are performed in the same or separate tubes. In the two-step method, RNA is first transcribed into cDNA in a reaction using reverse transcriptase. WebThe principle of cDNA microarray is illustrated in Figure 34.1. In brief, cDNA clones, which generally range from several hundred base pairs to several kilobases, are printed on a glass surface, either by mechanical or inkjet microspotting.
