The kit adopts a new efficient and fast hot-start amplification enzyme GoldStar Taq DNA Polymerase, which effectively avoids non-specific amplification caused by non-specific binding of primers and templates or primer dimerization at room temperature. This product realizes accurate quantification of Y chromosome and can be applied in various fields such as genetic mapping, species polymorphism research, disease gene localization, paternity testing and forensic analysis.ROX dye is used to correct the fluorescence signal error generated between wells of a quantitative PCR instrument, and is generally used in Real Time PCR amplifiers from ABI, Stratagene, and other companies. The excitation optics vary from instrument to instrument, so the concentration of ROX dye must be matched to the corresponding fluorescence quantitative PCR instrument.Instruments that do not require ROX calibration: Roche LightCycler 480, Roche LightCyler 96, Bio-rad iCyler iQ, iQ5, CFX96, etc.Instruments requiring Low ROX calibration: ABI Prism7500/7500 Fast, QuantStudio®3 System, QuantStudio®5 System, QuantStudio®6 Flex System, QuantStudio®7 Flex System, ViiA 7 System, Stratagene Mx3000/Mx3005P, Corbett Rotor Gene 3000, and others.Instruments requiring High ROX calibration: ABI Prism7000/7300/7700/7900, Eppendorf, ABI Step One/Step One Plus, etc.Note: High Rox and Low Rox are formulated as described in Method of Use 3.Scope of applicationThis product is suitable for quantitative testing of male Y chromosome DNA in scientific research, clinical, forensic medicine and paternity testing.Usage1. Amplification template preparationThe library samples to be detected were diluted with TE (10 mM Tris-Cl, pH 8.0, 1 mM EDTA), and the concentration after dilution was as close as possible to the range of 0.05-10 ng/µL. 4°C on ice was set aside.2. Standard dilution: according to the following table, firstly dilute Human DNA Standard (100ng/uL) with TE to make 5 standards of different concentrations according to the table below. 10ng/µL of DNA Standard 1 (Std.1) can be stored stably at -20℃ for 1 month; Std2-5 can only be used on the same day, and should be placed at 4℃ or on ice when not in use for the time being after preparation. When Std2-5 are not used temporarily after preparation, they should be stored at 4℃ or on ice.Standard sampleCorresponding concentration(ng/µl)Minimum Dilution Volume (Unit：µl）Std.11010 [100 ng/µl DNA Standard]+ 90 TEStd.22.520 [Std. 1] +60 TEStd.30.62520 [Std. 2] +60 TEStd.40.1562520 [Std. 3] +60 TEStd.50.039062520 [Std. 4] +60 TE3. qPCR reaction system preparationBefore preparation, the cryopreserved reagents to be used were completely melted and mixed by inverting several times, then centrifuged briefly and prepared. Standards and templates were diluted as described above and prepared.The base reaction system for 20 µL was as follows:Reagent20 µl Reaction system2×GoldStar Probe Mixture10 µlProbe Primer Mix3 µlTemplate4 µlddH₂O3 µlNote: High ROX model: add 1 µL of 50×High ROX per 50 µL of reaction system; Low ROX model: add 1 µL of 50×High ROX per 500 µL of reaction system.A sufficient amount of reaction system mixture was prepared according to the need, and after the reaction system was prepared and mixed thoroughly, it was added to the reaction wells in a volume of 16 µl per well. Then add the prepared standards and diluted samples into the corresponding reaction wells, the amount of addition is 4µL/well. TE was added to the blank control tube, and the same amount was added at 4 µL/well.It is recommended to use 20 µL for the reaction, if you need to perform a smaller system reaction, reduce the system components in equal proportion.4. qPCR reaction programThe PCR mix of this kit contains a FAM fluorescent probe for the target gene and a VIC fluorescent probe with internal reference to Internal PCR Control (IPC). qPCR program with dual fluorescence of hydrolyzed probes needs to be selected for the assay. Please follow the instructions of the instrument used to set up the qPCR program, and the PCR temperature conditions are as follows:1. Standard curve productionThe standard curve was plotted with reference to the Excel sheet for data processing. The correlation coefficient R2 of the standard curve should be not less than 0.98, and the slope should be located between -3.1 and -3.6 when the Ct value is used as the longitudinal coordinate. If the parameters of the standard curve are unreasonable, it is recommended to repeat the experiment.DNA Standard NameDNA Standard Concentration（ng/µL）DNA Standard 110DNA Standard 22.5DNA Standard 30.625DNA Standard 40.15625DNA Standard 50.03906252. Analysis of results and calculation of concentrationsThe Ct difference between experimental replicate wells for FAM signaling of the target gene should be no more than 0.3, otherwise invalid data need to be deleted or the experiment needs to be repeated, do not use Ct outside the valid Ct range of the standard curve to calculate the concentration of the sample.For specific calculations, please refer to the data processing Excel for this product.If the FAM signal is abnormal, the VIC signal of the internal reference Internal PCR Control (IPC) needs to be analyzed to confirm whether the PCR reaction process is abnormal. If the Ct value of the sample null VIC is significantly larger than that of the standard or blank control wells, it means that the sample inhibits the PCR reaction.matters needing attention1. Before testing, these instructions should be read in detail. It should be operated by personnel with professional experience or qualified by training.2. For use, please mix gently by turning up and down, avoid foaming as much as possible, and use it after centrifugation for a short period of time.3. Avoid repeated freezing and thawing of the product, repeated freezing and thawing may degrade the performance of the product.4. When preparing the reaction solution, please use new or non-contaminated tips and centrifuge tubes to prevent contamination as much as possible... Read More |
