Multiplex PCR allows for the simultaneous amplification of more than one PCR product by the inclusion of multiple primer pairs in a single reaction. This approach saves time, is more economical in the consumption of reagents than standard PCR, and makes it possible to use valuable samples efficiently. Multiplex PCR Assay Kit Ver. 2 includes an enzyme mix for high-speed priming and a buffer (with Mg2+ and dNTPs) optimized for increased specificity of primer annealing.
