Quantitative pcr equipment perspective 2. The illustration shows a benchtop real-time PCR thermal cycler with a hinged heated lid, sample block under the cover, control keypad, display screen, and indicator lights in three-quarter view. In molecular biology and clinical diagnostics, this laboratory instrument performs qPCR (quantitative polymerase chain reaction) and RT‑qPCR (reverse transcription quantitative PCR) to amplify and quantify nucleic acids from biological samples. Functionally, it monitors fluorescence to generate amplification curves and Ct (cycle threshold) values, enabling quantification of target genes within DNA or cDNA extracted from cells and tissues—linking molecular targets (genes) to organismal-level analyses. The device is typically situated on a laboratory bench; no species or human subjects are depicted.
