Pcr light source
Splet31. jul. 2015 · The light source was an array of off-the-shelf LEDs positioned beneath the PCR wells. The peak wavelength of the blue LED light was 450 nanometers, tuned to get the most efficient light-to-heat ... SpletPCR uses heating and cooling cycles to cause DNA melting and replication. Here’s how PCR works: The process uses heat to separate the two strands of DNA, and then temperatures are cooled, and primers bind to the DNA. …
