TaqMan Universal Master Mix II is a convenient mix of components (except primers, probes, template, and water) necessary to perform a real-time polymerase chain reaction (PCR). Use TaqMan Universal Master Mix II to amplify complementary DNA (cDNA) and DNA targets for a variety of applications, including quantitation and genotyping.
Reliable qPCR PerformanceThis master mix is optimized for high accuracy and sensitive quantification in qPCR applications, ensuring reliable results even at low target concentrations. The inclusion of carefully balanced buffer components and AmpliTaq Gold DNA Polymerase leads to consistent amplification, enabling users to trust their gene expression, genotyping, or microRNA analysis outcomes.
Carryover Contamination PreventionThe incorporation of Uracil-N-Glycosylase (UNG) significantly reduces the risk of PCR carryover contamination by degrading any uracil-containing DNA from previous PCR reactions. This feature is crucial for preventing false positives in sensitive qPCR experiments, especially in high-throughput laboratory environments with repeated sample handling.
Ready-to-Use ConvenienceDelivered as a premixed liquid reagent, this master mix reduces preparation time and user error. Simply mix by gentle inversion and it's ready for immediate use. The master mix is compatible with both manual and automated pipetting systems on a wide range of real-time PCR instruments, which makes it ideal for various laboratory workflows.
Storage and StabilityTo maintain its stability and performance, the master mix should be stored at -15C to -25C, protected from light, and avoid repeated freeze-thaw cycles. It is shipped on dry ice for optimal preservation, with a shelf life of 12 months from the date of manufacture, supporting extended use in research laboratories.
FAQ's of Thermo Fisher Scientific Applied Biosystems TaqMan Universal Master Mix II, with UNG:
Q: How do I properly mix the TaqMan Universal Master Mix II with UNG before use?
A: Gently invert the master mix several times to ensure homogeneity. Do not vortex the solution, as vigorous mixing can introduce bubbles and negatively affect the performance in qPCR assays.
Q: What types of assays are compatible with this master mix?
A: The mix is compatible with all TaqMan Gene Expression, Genotyping, and MicroRNA Assays, making it suitable for a wide range of qPCR applications, including gene expression studies and pathogen detection.
Q: When and why should I use a master mix containing UNG?
A: UNG (Uracil-N-Glycosylase) is included to prevent PCR carryover contamination by degrading uracil-containing DNA from previous experiments. It is especially beneficial in environments where cross-contamination risk is a concern or when working with high-sensitivity qPCR assays.
Q: Where should I store the TaqMan Universal Master Mix II with UNG, and how should it be handled upon arrival?
A: Store the master mix at -15C to -25C immediately upon arrival. Protect it from light, and avoid repeated freeze-thaw cycles to ensure product integrity and consistent qPCR results.
Q: What are the benefits of using a premixed, ready-to-use master mix?
A: Using a premixed, ready-to-use master mix reduces preparation time, minimizes pipetting errors, and ensures consistent component concentrations for reproducible qPCR results. It simplifies the workflow and increases laboratory efficiency.
Q: How is the product quality monitored and tracked?
A: Each lot of the master mix undergoes stringent batch-specific quality control and documentation, ensuring reliable performance and traceability for every batch manufactured.
