It was first developed in the 1980s.The QIAGEN Multiplex PCR Master Mix includes HotStarTaq DNA Polymerase and a unique PCR buffer containing the novel synthetic Factor MP. Together with optimized salt concentrations, this additive stabilizes specifically bound primers and enables efficient extension of all primers in the reaction without the need for optimization. Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled through a series ...e. Mix reactions well and spin if needed. f. Cap tubes or seal the PCR plate and label (according to instrument requirements). (Make sure the labelling does not obscure instrument excitation/detection light path.) 3. Run samples as per instrument manufacturer recommendations. Examples of standard and fast cycling have been included below.

signal the presence of amplified DNA template. Thus, a real-time PCR instrument exposes the reaction mix to a specific wavelength of light (excitation), and the reaction emits light (emission) of a different wavelength. The detection/filter channel within a real-time PCR instrument reads a specific wavelength while blocking others.
