Abstract

In a method for performing a hot start polymerase chain reaction, a reaction mixture including a primer, a template molecule, and a buffer—but no polymerase enzyme—is loaded in a reaction channel of a microfluidic device. An electrical current is applied to heat the reaction channel. A polymerase enzyme is delivered into the reaction channel, and the reaction channel is subjected to conditions such that the hot start polymerase chain reaction is performed. In a method for performing a temperature mediated reaction, a first component of the temperature mediated reaction is loaded in a reaction channel of a microfluidic device. An electrical current is applied to heat the reaction channel. A second component of the temperature mediated reaction is delivered into the reaction channel, and the reaction channel is subjected to conditions such that the temperature mediated reaction is performed.
