Platinum ® Quantitative PCR SuperMix-UDGCat. no. 11730-017 Size: 100 reactions Cat. no. 11730-025 Size: 500 reactions Store at –20°C Description Platinum® Quantitative PCR SuperMix-UDG is a ready-to-use cocktail containing all components, except primers, for the amplification and detection of DNA in real-time qPCR. The SuperMix combines the automatic “hot-start” technology of Platinum® Taq DNA polymerase with integrated UDG carryover prevention technology to provide optimal performance witha variety of qPCR detection technologies, including LUX™ Fluorogenic Primers and TaqMan® probes (1–4). Volumes are provided for 100 or 500 amplification reactions of 50 μl each. The SuperMix is supplied at a 2X concentration and contains Platinum® Taq DNA polymerase, Tris-HCl, KCl, 6 mM MgCl2,400 μM dGTP, 400 μM dATP, 400 μM dCTP, 800 μM dUTP, uracil DNA glycosylase (UDG), and stabilizers. • Platinum® Taq DNA polymerase is recombinant Taq DNA polymerase complexed with a proprietary antibody that blockspolymerase activity at ambient temperatures. Activity is restored after the denaturation step in PCR cycling, providing an automatic hot start in PCR for increased sensitivity, specificity, and yield (5, 6). • UDG and dUTP in the SuperMix prevent the reamplification of carryover PCR products between reactions (7). dUTP ensures that any amplified DNA will contain uracil, while UDG removes uracil residues from single- or double-stranded DNA, preventing dU-containing DNA from serving as template in future PCRs (8). A UDG incubation step before PCR cycling destroys any contaminating dU-containing product from previous reactions. UDG is then inactivated by the high temperatures during normal PCR cycling, thereby allowing the amplification of genuine target sequences. Magnesium chloride (50 mM) is provided as a separate component to allow adjustment of the magnesium concentration for optimal performance. ROX Reference Dye is included as a separate component to normalize the fluorescent signal between reactions, for instruments that are compatible with this option. Note: This kit is designed for use with fluorogenic primers or probes. For detection using SYBR® Green I dye, we recommend Platinum® SYBR® Green qPCR SuperMix-UDG (see Additional Products, below).Component 100-rxn Kit 500-rxn Kit Platinum® Quantitative PCR SuperMix-UDG 2 × 1.25 ml 12.5 ml 50 mM Magnesium Chloride 1 ml 2 × 1 ml ROX Reference Dye 100 μl 500 μl Storage Components may be stored at either -20ºC or 4ºC.

Guidelines and Parameters Instrument Compatibility This kit can be used with a variety of real-time instruments, including but not limited to the ABI PRISM® 7000, 7700, and 7900HT; the ABI 7300 and 7500 Real-Time PCR Systems; the ABI GeneAmp® 5700; the Bio-Rad iCycler™; the Stratagene Mx3000P®, Mx3005P™, and Mx4000®; the Corbett Research Rotor-Gene™; the MJ Research DNA Engine Opticon™, Opticon® 2, and Chromo 4™ Real-Time Detector; and the Cepheid Smart Cycler®. Template cDNA For two-step qRT-PCR, use 5 μl of undiluted or 10 μl of diluted cDNA generated from 10 pg to 1 μg of total RNA. For cDNA synthesis, we recommend SuperScript™ III First-Strand Synthesis SuperMix for qRT-PCR (see Additional Products, page 1). Note that detecting high-abundance genes in undiluted cDNA may result in very low CTs in qPCR, leading to reduced quantification accuracy. Prepare a dilution series of the cDNA template for the most accurate results. Plasmid and Genomic DNA Use 100 pg to 1 μg of genomic DNA or 10–107 copies of plasmid DNA in a 10-μl volume. Note that 1 μg of plasmid DNA contains 9.1 × 1011 copies divided by the plasmid size in kilobases. Magnesium Concentration Magnesium chloride is included in the SuperMix at a final concentration of 3 mM. This works well for most targets; however, the optimal concentration may range from 3 to 6 mM. If necessary, use the 50-mM magnesium chloride provided in the kit to increase the magnesium concentration, as shown below (the table assumes a 50-μl reaction containing 25 μl of SuperMix): For a Final MgCl2 Concentration of Add this Volume of 50-mM MgCl2 (per 50-μl Rxn) 4.0 mM 1 μl 5.0 mM 2 μl 6.0 mM 3 μl Decrease the amount of water in the reaction accordingly. ROX Reference Dye ROX Reference Dye can be included in the reaction to normalize the fluorescent reporter signal, for instruments that are compatible with that option. ROX is supplied at a 25 μM concentration, and is composed of a glycine conjugate of 5-carboxy-X-rhodamine, succinimidyl ester in 20 mM Tris-HCl (pH 8.4), 0.1 mM EDTA, and 0.01% Tween® 20. Use the following table to determine the amount of ROX to use with a particular instrument (per 50-μl reaction volume): Instrument ROX per 50-μl reaction Final Concentration ABI 7000, 7300 7700, 7900HT, and 7900HT Fast 1.0 μl 500 nM ABI 7500; Stratagene Mx3000™, Mx3005P™, and Mx4000™ 0.1 μl* 50 nM *To accurately pipet 0.1 μl per reaction, we recommend diluting ROX 1:10 immediately before use and use 1 μl of the dilution. Note: Platinum® Quantitative PCR SuperMix-UDG with ROX (Catalog nos. 11743-100 and 11743-500) includes ROX in the SuperMix at a 500 nM final concentration (see Additional Products, page 1) Multiplexing In multiplex applications, different reporter dyes are used to label separate primers or probes targeting different genes. For relative expression studies using multiplex PCR, the amount of primer for the reference gene (e.g., β-actin or GAPDH) should be limited to avoid competition with the sample gene. In general, the final concentration of the reference gene primer should be between 25 and 100 nM. A primer titration is recommended for optimal results. For best results using the following detection systems, the amplicon size should be 80–200 bp. LUX™ Primers LUX™ Primers are fluorogenic primers for qPCR that provide high sensitivity, high specificity, multiplexing capability, and melting curve analysis. LUX™ Primers are available separately and may be designed for specific targets using the D-LUX™ Designer. A final concentration of 200 nM per primer is effective for most reactions. Optimal results may require a primer titration between 100 and 500 nM. Dual-Labeled Probes A final probe concentration of 100 nM is effective for most reactions. The optimal concentration may vary between 50 and 500 nM. PCR primers used with probes should be designed according to standard PCR guidelines. A final concentration of 200 nM per primer is effective for most reactions. Page 3 General Protocol for ABI Instruments Follow the protocol below for qPCR using either LUX™ Primers or TaqMan® Probes on ABI real-time instruments. Note the separate cycling conditions for the ABI 7500 in Fast Mode, and the lower amount of ROX Reference Dye required for the ABI 7500 and 7500 Fast systems. This generic protocol may also be used for other real-time instruments. For protocols for specific instruments: [email protected]. A standard 50-μl reaction size is provided; component volumes can be scaled as desired (e.g., scaled down to a 20-μl reaction volume for 384-well plates). 1.

Page 4 Troubleshooting Problem Possible Cause Solution Signals are present in notemplate controls, and/or multiple peaks are present in the melting curve graph Template or reagents are contaminated by nucleic acids (DNA, cDNA) Use melting curve analysis if possible, and/or run the PCR products on a 4% agarose gel after the reaction to identify contaminants. To reduce the risk of contamination, take standard precautions when preparing your PCR reactions. Primer dimers or other primer artifacts are present Use melting curve analysis to identify primer dimers by their lower melting temperature if possible. Use validated primer sets or design primers/probes using dedicated software programs or primer databases. Check the purity of your primers by gel electrophoresis. If agarose gels are used, we recommend cooling the gels before visualization with intercalating dyes. No amplification curve appears on the qPCR graph There is no PCR product Run the PCR product on a gel to determine whether PCR worked. Then proceed to the troubleshooting steps below. No PCR product is evident, either in the qPCR graph or on a gel The protocol was not followed correctly Verify that all steps have been followed and the correct reagents, dilutions, volumes, and cycling parameters have been used. Template contains inhibitors, nucleases, or proteases, or has otherwise been degraded. Purify or re-purify your template. Primer design is suboptimal Verify your primer selection. Use validated primer sets or design primers/probes using dedicated software programs or primer databases. PCR product is evident in the gel, but not on the qPCR graph qPCR instrument settings are incorrect Confirm that you are using the correct instrument settings (dye selection, reference dye, filters, acquisition points, etc.) for your application. Problems with your specific qPCR instrument For instrument-specific tips and troubleshooting: [email protected] PCR efficiency is above 110% Template contains inhibitors, nucleases, or proteases, or has otherwise been degraded. Purify or re-purify your template. Inhibitors in the template may result in changes in PCR efficiency between dilutions PCR efficiency is below 90% The PCR conditions are suboptimal Verify that the amount of primers/probe you are using is correct and that the labeled primer or probe has not been exposed to direct light. Verify that the reagents you are using have not been freeze-thawed multiple times and have not remained at room temperature for too long. Multiplex reactions: Primer concentration may be limiting the rate of the reaction. Perform a single-plex reaction using the same primers and template to check efficiency. Then determine which primer set should be in limiting concentration. Typically, you should limit the amount of primer for the most abundant gene(s).
