1 Reliable PCR Components for Molecular Diagnostic Assays Terri McDonnell, MBA, PMP Senior Program Manager, Molecular Diagnostics March 2014

2 In this webinar we will: Discuss requirements for amplification components used in PCR-based MDx assays Introduce new family of GoTaq MDx DNA Polymerases Describe Promega MDx PCR component product portfolio Discuss customization options for MDx PCR components The products discussed in this presentation are intended for general laboratory use and are suitable for use as components of molecular diagnostic assays, where applicable country laws allow. The products themselves do not provide any diagnostic result. 2

10 Specifications Undetectable Nuclease Contamination Undetectable Nuclease Contamination Exonuclease No observable degradation of 1mg of Lambda DNA/Hind III Markers after incubation for 22 o C, followed by 45 o C in the presence of 15u Taq polymerase. Endonuclease Nicking No observable nicking of 0.5mg of supercoiled DNA after incubation for 22 o C, followed by 45 o C in the presence of 15u Taq polymerase. 10

11 Specifications Functionally Tested by Real-Time PCR Functionally Tested GoTaq MDx DNA Polymerase 1 unit of Taq polymerase quantitatively amplifies genomic DNA target meeting slope, y-intercept, and R 2 specifications. GoTaq MDx Hot Start Polymerase Amplify a hot-start model template to produce a single 1.5kb product, eliminating extraneous amplification products. In a non hot-start PCR, this template produces an additional 410bp amplification product. 11
