A Real-Time PCR System, also known as quantitative PCR (qPCR), is a cutting-edge laboratory instrument used for DNA and RNA amplification, detection, and quantification. Unlike traditional PCR machines, Real-Time PCR systems provide real-time monitoring of DNA amplification using fluorescent dyes or probes. This technology is widely used in medical diagnostics, genetic research, forensics, and pharmaceutical applications due to its high sensitivity, accuracy, and speed.
What is a Real-Time PCR System?
A Real-Time PCR System enables researchers to monitor the amplification process cycle by cycle, allowing for precise quantification of nucleic acids. This system uses fluorescence-based detection methods to analyze gene expression, mutations, and infectious diseases in real-time.
Types of Real-Time PCR Systems
🧬 Single-Channel qPCR – Measures fluorescence at one specific wavelength for basic DNA detection.
🌈 Multiplex qPCR – Detects multiple DNA targets simultaneously using different fluorescent dyes.
