3 I. Description Premix Ex Taq (Probe qpcr) is designed for real-time PCR (qpcr) detection with the TaqMan *1 probe. *2 This product is also suitable for high-speed PCRs. Premix Ex Taq allows accurate target quantification and detection over a broad dynamic range and makes it possible to conduct highly reproducible and reliable real-time PCR analyses. The product is supplied premixed at 2X concentration to facilitate easy preparation of reaction mixtures. The 2X premixed reagent also contains Tli RNase H, a heat-resistant RNase H, to minimize PCR inhibition by residual mrna in reactions with cdna as a template. A combination of TaKaRa Ex Taq HS, a hot start PCR enzyme that uses an anti-taq antibody, and a buffer optimized for real-time PCR results in excellent suppression of non-specific amplification, high amplification efficiency, and high detection sensitivity in real-time PCR analyses. Advantages: (1) This product allows rapid and accurate detection and quantitative gene expression analysis by real-time PCR. (2) The premixed reagent at 2X concentration makes pipetting easy. (3) Includes TaKaRa Ex Taq HS, which is designed for hot start PCRs. The buffer system has been optimized for real-time PCRs, offering excellent amplification efficiency and highly sensitive detection. (4) The 2X premixed reagent includes Tli RNase H, a heat-resistant RNase H, to minimize PCR inhibition by residual mrna in reactions using cdna template.

4 II. Principle This product is used to perform PCR amplifications with TaKaRa Ex Taq HS. Signal from amplification of PCR products is monitored using a TaqMan probe. 1. PCR PCR enables amplification of specific target gene fragments from a minute amount of DNA. Through repeated cycles of DNA heat denaturation, primer annealing, and extension by DNA polymerase, PCR allows up to a million-fold amplification of the target gene fragments within a short time. For amplifications, this product uses the hot start PCR enzyme TaKaRa Ex Taq HS, which prevents non-specific amplifications. TaKaRa Ex Taq HS Polymerase prevents mispriming or formation of primer dimers during reaction mixture preparation or other pre-cycling steps and allows high-sensitivity detections. 2. Fluorescence Detection TaqMan probe technique Oligonucleotides modified by a 5 fluorophore (e.g., FAM) and a 3 quencher (e.g., TAMRA) are added to the reaction system. Under annealing conditions, the TaqMan probe hybridizes specifically to the template DNA. Fluorescence of the fluorophore is suppressed by the quencher. During the extension reaction, the 5 3 exonuclease activity of Taq DNA polymerase degrades the hybridized TaqMan probe, releasing quencher suppression and allowing fluorescence detection. 1) Heat denaturation Probe Primer Fluorophore F Q Quencher 2) Primer annealing/probe hybridization Polymerase F Hybridization Q 3) Extension F Q F Q 4 URL:

6 VII. Protocol 1. General Overview of PCR Reaction Conditions Initial denaturation Step Temperature Time Detection Comment Initial denaturation sec. Off Generally, 95 for 30 sec. is sufficient for initial denaturation in most cases, even with difficult to denature templates such as circular plasmids and genomic DNAs. This procedure may be extended to 1-2 min. at 95 depending on template condition. Prolonged denaturation may inactivate the enzyme. Therefore, do not perform denaturation for more than 2 min. Shuttle PCR (2 step PCR) number of cycles: cycles Step Temperature Time Detection Comment Denaturation sec. Off Annealing/ extension sec. (31, 34 sec.) * On Generally the amplification product size for real-time PCRs does not exceed 300 bp. Therefore, 95 for about 3-5 sec. is usually sufficient. When optimizing reaction conditions, evaluate results using annealing/ extension temperature in the range of If poor reactivity occurs, increasing incubation time for this step may improve results. *: Some apparatuses by Life Technologies do not allow a detection-step setting of 30 sec. or shorter. ABI PRISM 7700 allows a setting of 30 sec. or longer. ABI PRISM 7000 and Applied Biosystems 7300 allow a setting of 31 sec. or longer. Applied Biosystems 7500 allows a setting of 34 sec. or longer. 2. Protocol using Thermal Cycler Dice Real Time System II 1.

7 *1: *2: *3: Final primer concentration of 0.2 μm is most likely to yield good results. However, should further optimization be required, try adjusting primer concentrations in the range of μm. The probe concentration varies depending on the model of real-time PCR apparatus used and the fluorescent labeling dye of the probe. Refer to the instrument manual and the probe data sheet to determine the appropriate concentration. When using the Thermal Cycler Dice Real Time System II, use a final concentration in the range of μm. Optimal template quantity depends on the target copy concentration of the template solution. Prepare and test serial dilutions to select an appropriate quantity. Use no more than 100 ng of DNA template. When using cdna as a template in RT-PCRs (RT reaction mixture), template solution volume should not exceed 10% of the PCR reaction mixture (e.g., no more than 2.5 μl cdna template solution for a 25 μl PCR reaction). 2. Start the reaction. The recommended protocol for PCR reactions is the shuttle PCR standard protocol shown below. You may set the annealing/extension time to between 20 and 30 sec., but first try 30 sec., which generally yields stable results. (Refer to General Overview of PCR Reaction Conditions on page 6.)

Prolonged denaturation can affect amplification efficiency and quantification accuracy. 3. After the reaction is complete, assess the amplification curve and create a standard curve if a quantitative determination will be performed.
