WebOct 17, 2024 · Real-time detection of PCR products can be achieved through the use of either: 1) DNA-binding dyes or 2) fluorescent PCR primer- and probe-based chemistries. As their name implies, DNA-binding dyes are non-specific fluorescent dyes that intercalate with any double-stranded DNA (dsDNA) molecules. WebDigital PCR steps and applications. Step 1. Sample preparation. As with any genomic analysis, a sample of nucleic acid must be obtained. For genotyping applications, a sample of the genomic DNA (gDNA) needs to be purified from the tissue or sample of interest.

WebCalibrate the Real-Time PCR Instrument for Dyes and Fluorophores Prior to starting a qPCR experiment, verify that the real-time PCR instrument is compatible and calibrated correctly for the dyes and fluorophores chosen. CFX Manager™ software has a Dye Calibration Wizard with an easy guide to calibration (Tools > Dye Calibration Wizard). WebFluorophores (or fluorochromes) are commonly used in conjugation with antibodies as detection reagents in applications such as flow cytometry. Fluorophores can absorb and emit light within a range of wavelengths, normally referred to as the absorbance (excitation) and emission spectra.
