MegaMix Platinum qPCR Mastermix (Probe Based)

What is MegaMix Platinum qPCR Mastermix?
Answer: MegaMix Platinum is a 2X probe-based qPCR mastermix designed for sensitive, reliable real-time PCR. It contains chemically modified Hot Start Taq DNA polymerase in an optimised PCR buffer and is designed for both singleplex and multiplex probe-based qPCR applications, including low-copy DNA targets.

Is MegaMix Platinum a probe-based qPCR master mix?
Answer: Yes. MegaMix Platinum is specifically designed for probe-based qPCR and is optimised for assays using dual-labelled hydrolysis probes, including TaqMan and Scorpion probes.

Can MegaMix Platinum be used for multiplex qPCR?
Answer: Yes. MegaMix Platinum is optimised for multiplex qPCR and is designed to provide reliable amplification when detecting multiple targets in the same reaction. The product datasheet specifically highlights multiplexed reactions involving four or five targets.

Is MegaMix Platinum compatible with TaqMan assays?
Answer: Yes. MegaMix Platinum is compatible with TaqMan assays and other dual-labelled hydrolysis probe-based qPCR assays.

Is MegaMix Platinum compatible with Scorpion probes?
Answer: Yes. MegaMix Platinum is optimised for probe-based assays including Scorpion probes, making it suitable for a range of real-time PCR assay formats.

Can MegaMix Platinum detect low-copy DNA targets?
Answer: Yes. MegaMix Platinum has an optimised buffer system designed for amplification of low-copy DNA targets and is formulated to provide high sensitivity across a wide dynamic range.

Can MegaMix Platinum detect viral DNA?
Answer: Yes. MegaMix Platinum can be used for qPCR detection and quantification of viral DNA. The appropriate primers, probe and sample preparation method should be selected for the specific viral target.

Can MegaMix Platinum be used with cDNA?
Answer: Yes. MegaMix Platinum can be used with cDNA templates for probe-based qPCR, including applications such as gene expression analysis. For one-step RT-qPCR from RNA, a dedicated MegaMix Platinum Probe RT-qPCR Kit containing reverse transcriptase is available.

Is MegaMix Platinum suitable for gDNA detection?
Answer: Yes. MegaMix Platinum is suitable for probe-based qPCR using genomic DNA (gDNA) as the template, including target detection and quantification applications.

Can MegaMix Platinum be used for fast qPCR?
Answer: Yes. MegaMix Platinum is compatible with fast qPCR cycling conditions and has been optimised for rapid two-step amplification. Actual run time will depend on the primers, probe, instrument and cycling protocol used.

Can MegaMix Platinum be used for standard qPCR cycling?
Answer: Yes. MegaMix Platinum is compatible with both standard and fast qPCR cycling conditions, providing flexibility across different real-time PCR instruments and assay workflows.

Does MegaMix Platinum contain Hot Start Taq?
Answer: Yes. MegaMix Platinum contains a chemically modified Hot Start Taq DNA polymerase. The Hot Start formulation helps support specific amplification by reducing unwanted activity before the initial high-temperature activation step.

Does MegaMix Platinum contain UNG?
Answer: UNG is available as a MegaMix Platinum formulation option. Formulations containing UNG also incorporate dUTP to support PCR carryover contamination control. Therefore, users should select the UNG-containing formulation when this feature is required.

Can MegaMix Platinum help prevent PCR carryover contamination?
Answer: Yes. When the UNG-containing formulation is used, thermolabile UNG together with dUTP helps prevent PCR amplicon carryover contamination. The UNG is active before amplification and is irreversibly inactivated during the high-temperature cycling step.

Which ROX formulation should I use?
Answer: The appropriate ROX concentration depends on the qPCR instrument. MegaMix Platinum is available with ROX options suitable for different instrument requirements. As a general guide, low-ROX instruments require a lower ROX concentration, while high-ROX instruments require a higher concentration. Always check the requirements of your specific qPCR instrument before selecting the formulation.

Is MegaMix Platinum suitable for multiplex assays?
Answer: Yes. MegaMix Platinum is particularly well suited to multiplex probe-based assays. It is optimised for multiplex reactions using dual-labelled hydrolysis probes and is designed to support simultaneous detection of multiple targets without compromising amplification performance.

Can MegaMix Platinum be used to develop qPCR diagnostic kits?
Answer: Yes. MegaMix Platinum can be used as a component in the development of probe-based qPCR assays and diagnostic kit prototypes. It is designed for assay development and supports multiplex, TaqMan and Scorpion probe formats. However, the standard MegaMix Platinum product is supplied for research use only and is not, by itself, a validated clinical diagnostic product.

How does MegaMix Platinum compare with dye-based qPCR?
Answer: MegaMix Platinum uses sequence-specific probes for target detection, whereas dye-based qPCR uses an intercalating fluorescent dye that binds double-stranded DNA. Probe-based detection can provide greater target specificity and is particularly useful for multiplex assays, where several targets need to be distinguished in the same reaction.

How does MegaMix Platinum compare with MegaMix Emerald?
Answer: MegaMix Platinum is designed for probe-based qPCR using assays such as TaqMan and Scorpion, while MegaMix Emerald is a dye-based qPCR mastermix containing MicroGREEN intercalating dye. MegaMix Platinum is therefore the appropriate choice when sequence-specific probe detection or multiplex probe-based qPCR is required, whereas MegaMix Emerald is suited to dye-based qPCR and applications such as melt-curve analysis.

Why choose MegaMix Platinum for probe-based qPCR?
Answer: MegaMix Platinum combines high sensitivity with flexibility for probe-based qPCR. It supports singleplex and multiplex assays, including TaqMan and Scorpion probes, is optimised for low-copy DNA targets, works with both standard and fast cycling conditions, and is available with options such as UNG and ROX to suit different assay and instrument requirements.
