2 I. Description: One Step SYBR PrimeScript TM RT-PCR Kit is designed for Real-Time One Step RT-PCR including SYBR Green I* 1, * 2. RT-PCR can be performed all in a single tube subsequently, therefore the operation is simple, and it minimizes the risk of contamination. Also, Amplified products are monitoring in real time, so there is no need to verify them through electrophoreis after PCR. This kit is suitable for detection of tiny amount of RNA like RNA virus. This kit uses PrimeScript TM RTase, which has excellent extendibility and can efficiently synthesize cdna in short time period, and TaKaRa Ex Taq TM HS, high efficiency hot start PCR enzyme, and they are optimized for one step RT-PCR. Combing the TaKaRa Bio RT-PCR technology with these enzymes allow this kit to have a more efficient goin of RT-PCR product. Applicable real time PCR instruments; ABI PRISM 7000/7700/7900HT, 7300/7500 Real-Time PCR System (Applied Biosystems) LightCycler (Roche Diagnostics), and other Smart Cycler System* 3 /Smart Cycler II System* 3 (Cepheid) Thermal Cycler Dice TM Real Time System (TaKaRa Cat.#TP800) *1.

Principle: One Step SYBR PrimeScript TM RT-PCR Kit perform cdna synthesis from RNA using reverse transcriptase, PrimeScript TM RTase, and PCR amplification by TaKaRa Ex Taq TM HS within one tube continuously. PCR amplification products are monitored real time by SYBR Green I. 1. PCR PCR is a technique that amplifies only targeted section of gene from small amount of DNA. One cycle of PCR includes Heat denaturation of DNA, annealing of primer, and extension of DNA polumerase. By repeating this process, PCR allows amplification of targeted gene segment in million times in short time period. Use of Hot Start PCR enzyme, TaKaRa Ex Taq TM HS, for amplification made this kit possible to avoid miss-priming prier to the cycle during preparation of reagents, and nonspecific amplification caused by primer dimmer and possible to do high quality detection. 2

3 2. RT-PCR Although RNA would not be a direct template of PCR, PCR can be applied for RNA analysis when cdna were synthesized from RNA with reverse transcriptase. This is RT-PCR and is a high quality detection of RNA. This kit uses One Step RT-PCR. The principle of this is shown in next page. For One Step RT-PCR, use Specific Primer (Reverse) for PCR, and do reverse transcription. Then synthesized cdna as a template, do Specific primer (Forward, Reverse) PCR amplification.

4 3. Fluorescent spectrophotometer method [Intercalator method] This method detect fluorescence which produced in the amplification process by adding reactants (for example Intercalater: SYBR Green I) that fluoresces by bonding to double strand of DNA to the reactive system. It fluoresces when intercalater bound with double stranded DNA that is synthesized by polymerase reaction. From detecting this fluorescence, not only quantity of amplified DNA, but also, the melting point could be measured. 1) Heat denaturation Primer Intercalater (Fluorescent substance) 2) Primer annealing Polymerase 3) Extension III.

5 IV. Storage: X One Step SYBR RT-PCR Buffer III should be protected from light. V. Features: (1) One Step RT-PCR made accurate and rapid analysis of RNA virus or small amount of RNA possible. (2) For PCR, enzymes for Hot Start TaKaRa Ex Taq TM HS, high efficiency hot start PCR enzyme, is used. Buffer system is optimized for Real-Time PCR, thus amplification is effective and high quality detection is possible. Moreover, One Step SYBR RT-PCR Buffer III is a 2x concentration of premix with SYBR Green I, so the preparation of reactants is simple. VI. Note: Followings are protocol for this kit. Please read it carefully before you use the kit. (1) When mixing reagents for PCR, mix enough for 10 reactions for the master mix. Using master mixes allows accurate reagent dispensing, minimized reagent pipetting errors, and no repeat dispensing of the each reagent. This helps to minimize variation of the data from experiment to experiment. (2) PrimeScript TM RT Enzyme Mix II, TaKaRa Ex Taq TM HS should be mixed gently. Avoid generating bubbles! Gently spin down the solution prior to pipetting. Pipet the enzymes slowly as the enzyme contains 50% glycerol and is very viscous. (3) Keep the enzyme at - 20 until just before use and return into the freezer promptly after use. (4) Use new disposable pipette tips to avoid contamination between samples for transferring reagent. (5) Use the specific primer in this kit for reverse transcription. Random Primer or Oligo-dT Primer should not be used. 5

PCR Reaction Condition Shuttle PCR Step Temp. Time Detection Remark Denature 95 C 3~5 sec. Off Annealing/ 60~66 C 20~30 sec. On Extending Since the target size amplified for real time PCR is generally shorter than 300 bp, the denaturation at 95 for 3-5 seconds is a sufficient condition. Please try at 60 for 20 seconds at first. The temperature should be optimized within the range of if optimization is required. When reaction does not proceed efficiently, extened the time or change the reaction into 3 step PCR. 3 step PCR Step Temp. Time Detection Remark Denature 95 3~5 sec. Off Annealing 55~60 10~20 sec. Off Extending 72 6~15 sec. On Since the target size amplified for real time PCR is generally shorter than 300 bp, the denaturation at 95 for 3-5 seconds is a sufficient condition. Please try at 55 for 10 seconds at first. When non-specific amplified product generate or when the amplification efficiency is low, it can be solve with the optimization of annealing temperature. Longer annealing time may sometimes improve the amplification efficiency. When the amplified size is less than 300 bp, the time should be determined within the range of 6-15 seconds. Longer extension time can cause non-specific amplification. Cycle: 30~45cycles 10 *1: Detection step must be set at more than 30 seconds for device of Applied Biosystems. For 7700 and 7900HT should be set at 30 seconds, 7000 and 7300 should be set at 31 seconds, and 7500 should be set at 34 seconds.

12 IX. Appendix: A. Preparation of RNA sample This kit is designed to perform the reverse transcription of RNA to cdna and subsequent amplification. It is important to use high purity of RNA sample for better yields of cdna synthesis. So, it is essential to inhibit cellular RNase activity and also to prevent contamination with RNase derived from equipment and solutions used. Extra precaution should be taken during the sample preparation, including use of clean disposable gloves, dedication of a table exclusively for RNA preparation, and avoiding unnecessary speaking during assembly, to prevent the RNase contamination from operates sweat or saliva. [ Equipment ] Disposable plastic equipment shall be used. Glass tools should be treated with the following protocol prior to use. (1) Hot-air sterilization (180, 60min). (2) Treatment with 0.1% DEPC at 37, for 12 hours followed by autoclaving at 120 C for 30 min. to remove DEPC. * It is recommended that all the equipment be used as the exclusive use for RNA preparation. [ Reagent ] All reagents to be used in this experiment must be prepared using tools which were treated as described in previous section (Hot-air sterilization [(180, 60min) or DEPC treatment], and distilled water must be treated with 0.1%DEPC and autoclaved. All reagents and distilled water should be used exclusively for RNA experiments. [ Preparation of RNA sample ] It is recommended to use highly purified RNA obtained by GTC (Guanidine thiocyanate) method, etc. 12

13 X. Guidline for designing of primer: It is essential to design primers which allow good reactivity for a successful real time PCR reaction. Please follow the guideline stated as below to design primers which offer high amplification efficiency and minimizes non-specific reaction. Amplification product Amplified size bp is most recommended. (Possible to amplify a target up of 300 bp.) Primer Length mer GC content 40-60% (45-55% is recommended.) Tm Tm values of Forward primer and Reverse primer must not largely differ. Tm value is calculated with the software for calucation of Tm value. e.g. OLIGO *1 : Primer 3 *2 : Sequence The sequence should not be partially rich in each base in the whole equence. Avoid including parts which has high GC or AT content, (especially 3' -end). Not include polypyrimidine (serial T/C sequence). Not include polypurine (serial A/G sequence). Sequence of 3' end The termini part of 3' should not have high content of GC or AT. It is recommended to be G or C at 3' end. It is not recommended to be T at 3' end. Complementarity Complementary sequence of more than 3 bases should not exist within a primer or even between primer pairs. Primer pair should not have a complementary sequence of more than 2 bases at the 3' end each. Specificity Specificity of primers should be confirmed through BLAST search. *3 *1: OLIGO TM Primer Analysis Software (Moleculor Biology Insights, Inc.) *2: Primer3 ( *3: 13
