qPCR (quantitative Polymerase Chain Reaction) is a powerful technique used to detect and measure specific DNA or RNA sequences in real time. It allows researchers to monitor gene expression, study microbial content, or track changes in samples with high sensitivity and accuracy. By using fluorescent signals during amplification, qPCR provides both qualitative and quantitative data. It is widely used in biotechnology for analyzing gene activity, validating experimental results, and supporting quality control in various workflows. With fast results and reliable performance, qPCR remains a key method in modern molecular analysis.
