qPCR (Quantitative PCR)

Quantitative PCR (qPCR) is a laboratory technique used to measure the amount of specific DNA or RNA in a sample. It amplifies the targeted genetic material while simultaneously tracking its progress in real-time, often using fluorescent dyes or probes that emit signals proportional to the amount of DNA produced. This allows scientists to determine how much of a particular gene or genetic sequence is present, which is useful in research, diagnostics, and monitoring diseases. qPCR is sensitive, precise, and faster than traditional methods, making it a vital tool in molecular biology.
