4 Important Parameters Template Using copies of plasmid DNA, 100pg to 1ug of genomic DNA or 1pg to 100ng of cdna. In order to acquire the best experiment result, the amplification length should be approximately bp. Primers Primer design is one of the most important parameters when using SYBR Green detection system. We strongly recommend using primer design software such as Oligo, Primer5. When designing primers, the 0primers length should be approximately 15-40bp. Optimal results may require a titration of primer concentrations between 100 and 500 nm. A final concentration of 200 nm per primer is effective for most reactions. Magnesium Concentration MgCl 2 is included in the SYBR Mix at a final concentration of 2 mm. This concentration works well for most targets; however, the optimal concentration may range from 2 to 6 mm. If necessary, use the 25 mm MgCl 2 provided in the kit to increase the concentration, as shown below. Final MgCl 2 concentration Add this volume of MgCl mm 2 ul 4.0 mm 4 ul 5.0 mm 6 ul 6.0 mm 8 ul 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. Use the following table to determine the amount of Rox Reference Dye to use with a particular instrument: Amount of ROX Reference Dye Intrument (50 )per 50 ul reaction(ul) ABI7000,7300,7300,7900HT, HT Fast ABI7500,Stratagene Mx3000, Mx3005P, and Mx Using of the kit 1 Defrosting the reagents(2 SYBR Mix ddh 2 O)in the kit at room temperature.

Add the samples as per 4-10ul each into PCR tubes above. 4 PCR Reaction Program your Real Time PCR as shown below. Optimal temperatures and incubation times may vary. Three step standard cycling program 94,2min; 94,10s; 60,15s; 72,30s,40cycles Choose F1 channels when collecting fluorescent signals and set fluorescent signals detecting at 72 Two step standard cycling program 94,2min; 94,10s; 60,30s; 40cycles Choose F1 channels when collecting fluorescent signals and set fluorescent signals detecting at 60 Before running, please adjust gain to make the F1 (SYBR Green I) background 20. Program your melting curve as shown below. 95,2min; 72,1min; 95,30s,step 0.5 /s; 30,1min Note: when user is selecting the PCR programme, the three step methods will be recommended for amplification. If the amplification result of two-step is the same as the one of three-step method, user also can use two-step method instead of three-step method for saving time. Result analysis and judgments 1 Input the concentrations of four positive References. Select fit point method to analyze. Confirm the base line (zero adjustment) by getting the fluorescent signals.

6 Make the noise limit just beyond the peak of the amplification curve (rule less noise line) of normal negative control; then do quantitative analysis. You could also adjust by yourself according to the condition of instrument s noises. 2 Please record the concentration or CT value of non-known sample after analysis. 3 There are auto and manual for users choosing in melting curve analysis and record Tm value after analysis. 4 Users also can use agarose gel electrophoresis to analyze specificity of PCR products Note: 1.Please read this manual carefully before beginning the experiment. 2.Don t touch hand directly when you use one-time consumable such as pipe and centrifuge tube. 3.Be caution during the whole process to ensure the accuracy of the experiment. After finishing the experiment, in order to avoid pollution, please use 75% alcohol to clear the worktable. 4 The melted reagent should be stored as shorten as possible, and store them in environment of -20 immediately after testing. 5. Please store reagent or PCR reaction system in shadow place due to the fluorescence dye contained 6. Nucleic acid is easy to be contaminated and resulted in to the trusted result, so user should strictly do the amplification experiment according to standard PCR process. Sample storage Please store the sample at -20 and avoid repeating frozen. Sample transportation Please transport the sample at or lower than 4.

7 Description Adopting nucleic acid amplification technique and combining intermediate fluorescence method, SYBR Green I real-time PCR can do detection and quantification on target gene fast and properly. The kit offers 2 SYBR Mix, including all components except for Taq DNA polymerase and primers. During operation, user can do real-time PCR reaction directly by adding primer, template and Taq DNA polymerase, which is very simple. SYBR Green I is one kind of fluorescence dye, which will excited fluorescence signal after specially inserted in dsdna molecule. In PCR reaction system, when SYBR Green I dye combine with dsdna, and excited with excited light, via testing strength of fluorescence, user can calculate the quantity of dsdna. The advantage of fluorescence dye is that: it can be used in testing any dsdna amplification, without design of probe, and make the testing method easier, meanwhile, it can decrease cost, what s more, user can analyze melt curve directly. As soon as the PCR test finish. By the analysis of melt curve, user can judge whether there are existing aberrance or non-specific amplification. The Max Absorb wave length of SYBR Green I is 497nm, the Max. Emission wavelength is about 520nm.
