Introduction to PCR LED Technology

PCR LED technology is a significant advancement in the realm of molecular diagnostics, particularly in the context of DNA amplification and analysis. PCR, or Polymerase Chain Reaction, is a laboratory technique used to amplify a specific segment of DNA. The process involves three main steps: denaturation, annealing, and extension. PCR LEDs play a crucial role in the detection of fluorescence signals that occur during the extension phase of PCR. These LEDs are engineered to emit light at a wavelength that corresponds to the excitation maximum of the dye used in the PCR reaction. Commonly used dyes include SYBR Green, EvaGreen, and FAM, each emitting light at different wavelengths. The precise wavelength of the PCR LED ensures optimal excitation of the dye, leading to more accurate and sensitive detection of DNA amplification.
