PCR Probe: A Key Tool in Molecular Biology
In the ever-evolving field of molecular biology, PCR probes play a crucial role in detecting and quantifying DNA sequences with exceptional precision. Whether you’re working in research, clinical diagnostics, or environmental studies, PCR probes are the cornerstone of reliable and sensitive polymerase chain reaction (PCR) assays. What is a PCR Probe? A PCR probe is a short, fluorescently labeled DNA or RNA sequence that binds specifically to a target DNA sequence during a PCR reaction. Unlike traditional PCR that uses primers alone, probes add an extra level of specificity and sensitivity. By incorporating fluorescence-based detection, PCR probes enable real-time monitoring of DNA amplification. Types of PCR Probes There are different types of PCR probes designed for various applications: TaqMan Probes : These probes rely on fluorescence quenching and emission. When the DNA polymerase cleaves the probe during amplification, the fluorophore is released, producing a detectable sig...
