After sample extraction, a PCR (Thermal Cycler) is usually used for the DNA amplification. The PCR (Polymerase Chain Reaction), is under the catalytic of DNA polymerase, to mother chain DNA as a template, with specific primers for the starting point of extension, through the degeneration, annealing, extending steps, with the parent chain template DNA replicate the complementary DNA child chain in vitro. We provide diverse models of the gradient PCR maschines (e.g. 32 wells, 96 wells and dual block PCRs) , which provide you an effective sample amplification according to your requirements.
