3 I. Description SYBR Premix Ex Taq II(Tli RNaseH Plus) is a kit specifically designed for intercalator-based realtime PCR using SYBR Green I *. It is supplied at a 2 concentration premixed with SYBR Green I at a concentration appropriate for real time monitoring, to facilitate easy preparation of reaction mixtures. The 2 premixed reagent also contains Tli RNaseH, a heat-resistant RNase H, to minimize PCR inhibition due to residual mrna in reactions with cdna as template. This product, with a modified buffer composition, offers a higher reaction specificity than that of SYBR Premix Ex Taq (Tli RNaseH Plus) (Cat. # RR420A) and enables accurate assays over a wider range. A combination of this buffer and TaKaRa Ex Taq HS (a hot start PCR enzyme that uses an anti- Taq antibody) allows highly reproducible and reliable real-time PCR analyses. Compatible instrument systems include: Thermal Cycler Dice Real Time System II (Cat. # TP900/TP960) Applied Biosystems 7500 Real-Time PCR System, Applied Biosystems 7500 Fast Real-Time PCR System, StepOnePlus Real-Time PCR System (Life Technologies) LightCycler /LightCycler 480 System (Roche Diagnostics) CFX96 Real-Time PCR Detection System (Bio-Rad) Note: For the Smart Cycler System/Smart Cycler II System (Cepheid Corporation), the use of SYBR Premix Ex Taq (Tli RNaseH Plus) (Cat. #RR420L) is recommended. * TAKARA BIO is under a license agreement with Molecular Probes Inc. for the use of SYBR Green I as a reagent for research purposes. SYBR is a registered trademark of Molecular Probes Inc. II. Principle This product is used for PCR amplifications with TaKaRa Ex Taq HS. PCR amplification products can be monitored in real time using SYBR Green I. TaKaRa Ex Taq HS, a hot start PCR enzyme, prevents non-specific amplifications derived from mispriming or primer dimer formation during reaction mixture preparation or other precycling steps and thereby makes high-sensitivity detection possible. Fluorescence detection intercalator method This method involves the addition of a reagent (intercalator: e.g., SYBR Green I) that emits fluorescence when bound to double-strand DNA in reaction mixtures, allowing the detection of fluorescence associated with amplification. Measuring the fluorescence intensity not only allows quantitative determination but also provides the melting temperature of amplified DNA. URL: 3

5 VI. Precautions before Use Read these precautions before use and follow them when using this product. 1. Before use, make sure the reagent is evenly mixed by gently inverting the tube several times without creating bubbles. Uneven reagent composition will result in inadequate reactivity. Do not mix by vortexing. When stored at 80ºC, SYBR Premix Ex Taq II (2 ) (Tli RNase H Plus), Bulk may develop a white to pale yellow precipitate. To dissolve the precipitate completely, briefly let the reagent stand protected from light at room temperature (below approximately 30ºC), followed by inverting the tube several times. The presence of precipitate is indicative of uneven reagent composition; make sure the reagent is evenly mixed before use. 2. Place reagents on ice immediately after they are thawed. 3. This product contains SYBR Green I. Take care to avoid exposure to strong light when preparing the reaction mixture. 4. Use fresh disposable tips to avoid any potential cross-contamination between samples when preparing or dispensing reaction mixtures. 5. TaKaRa Ex Taq HS is a hot start PCR enzyme with an anti-taq antibody that inhibits polymerase activity. Do not perform the pre-pcr incubation (5 to 15 minutes at 95 C) that is required with other companies chemically modified hot start PCR enzymes. The activity of TaKaRa Ex Taq HS decreases with longer heat treatment and the amplification efficiency and quantification accuracy can be affected. Even for the initial denaturation step, incubation at 95 C for 30 sec. is generally sufficient. URL: 5

13 VIII. Appendix (1) Optimization If the recommended conditions (shuttle PCR standard protocol) provided insufficient reactivity, follow the procedures below to optimize primer concentration and PCR conditions. In addition, other real-time PCR reagents in the Perfect Real Time series (Cat. # RR420A/B/L, RR091A/B) may greatly improve the reactivity. PCR conditions should be selected with consideration of both reaction specificity and amplification efficiency. A PCR system well balanced between these two aspects allows accurate assays over a wide range of concentrations. System with a high reaction specificity Non-specific amplifications such as primer-dimer formation are not observed in the no template control reactions. Non-specific amplification products (those other than the target product) are not generated. System with a high amplification efficiency Amplification product is detected at earlier cycles (lower C t value). PCR amplification efficiency is high (near the theoretical maximum of 100%). [Evaluation of primer concentration] The relationships between primer concentration and reaction specificity or amplification efficiency are as follows. Reducing the primer concentration raises reaction specificity. Increasing the primer concentration, on the other hand, raises amplification efficiency. (Primer concentration) Low (0.1 µm) High (1.0 µm) Reaction specificity High Low Amplification efficiency Low High [Evaluation of PCR conditions] To raise reaction specificity Raising the annealing temperature may improve reaction specificity. Optimize the annealing temperature while balancing specificity with amplification efficiency. [Shuttle PCR] Standard protocol 95ºC 5 sec 60ºC 30 sec Raise the annealing temperature 95ºC 5 sec up to 64ºC 30 sec To raise amplification efficiency Prolonging the elongation time or switching to a 3-step PCR may improve amplification efficiencies. Optimize using the steps below. [Shuttle PCR] Standard protocol 95ºC 5 sec 60ºC 30 sec Prolong the elongation time 95ºC 5 sec 60ºC >1 min [3-step PCR] 95ºC 5 sec 55ºC 30 sec 72ºC 30 sec Prolong the elongation time 95ºC 5 sec 55ºC 30 sec 72ºC >1 min Initial denaturation Generally, 95ºC for 30 sec is sufficient for initial denaturation procedures. This condition offers good reactivity in most cases, even with difficult to denature templates such as circular plasmids and genomic DNA. Denaturation may be extended to 1 to 2 minutes at 95ºC depending on the template. Prolonged heating may inactivate the enzyme. Therefore, do not heat for more than 2 minutes. URL: 13

14 [Relationship between reagent and reactivity] TAKARA BIO supplies three different real-time PCR reagents for SYBR Green assay. Their respective relationships with reaction specificity and amplification efficiency are as follows. SYBR Premix Ex Taq (Tli RNaseH Plus) (Cat. # RR420A/B/L) provides a high amplification efficiency and is suitable for high-speed reactions. SYBR Premix Ex Taq II (Tli RNaseH Plus) (Cat. # RR820A/B/L) and SYBR Premix DimerEraser (Perfect Real Time) (Cat. # RR091A/B, not available in all geographic locations) are effective in raising the reaction specificity.

(Amplification is possible up to 300 bp in length.) mer GC content 40-60% (preferably 45-55%) T m Make sure the forward primer and the reverse primer do not differ greatly in T m values. Use software specifically designed to determine T m values. OLIGO *1 : 63-68ºC Primer3 *2 : 60-65ºC Sequence Make sure that there are no sequence biases overall. Avoid having GC-rich or AT-rich regions in the sequence (particularly at the 3 end). Avoid having consecutive T/C pairings (polypyrimidine). Avoid having consecutive A/G pairings (polypurine). 3 end sequence Avoid having GC-rich or AT-rich regions at the 3 end. It is preferable to have a G or C as the terminal base at the 3 end. It is better to avoid a primer design with T as the terminal base at the 3 end. Complementation Avoid having any complementary sequences of 3 bases or more within a primer and between primers. Avoid having any complementary sequences of 2 bases or more at primer 3' ends.
