The Thermocycler is a laboratory equipment of molecular biology that allows the reaction of the polymerase chain (PCR) efficiently and quickly, by automatic and cyclic realization of the changes of temperature that are required for the amplification of a chain of deoxyribonucleic acid (DNA), from a thermostable enzyme. The PCR technique allows a small amount of DNA molecules to be amplified many times, exponentially.
Applications of thermocyclers
It is commonly used in medical and biological research laboratories, with a wide variety of applications, including detection of gene expression and hereditary diseases, identification of genetic fingerprints, gene cloning, paternity testing, DNA computing and diagnosis of infectious diseases. Thermocyclers are used for qualitative amplifications or to quantify the amount of amplified DNA.
