Внедрение продукции：

This product is a specialized reagent for Real-Time qPCR using the probe method. It contains an antibody-blocked hot-start enzyme that effectively suppresses non-specific amplification caused by primer misannealing or primer dimer formation at low temperatures, thereby enhancing the specificity of the amplification reaction. This product exhibits high amplification efficiency and detection sensitivity, allowing for the generation of a robust standard curve across a broad quantification range, Включение точного количественного определения. Более того, it is compatible with various fluorescence quantitative ПЦР instruments, including those from Applied Biosystems, Eppendorf, Bio-Rad, Roche, and other domestic brands.

Содержание продукта：

Примечание：ROX Reference Dye can be obtained separately or through the manufacturer to correct inter-well fluorescence signal discrepancies in certain company’s Real-Time PCR amplifiers. ROX Reference Dye I is suitable for ABI PRISM 7000/7700/7300/7900HT and Step One Plus Real-Time PCR Systems, и т. д.. ROX Reference Dye II is suitable for 7500 Real-Time PCR System, 7500 Fast Real-Time PCR System, Stratagene Mx3000P, Mx3005P, and Mx4000, и т. д.. The final concentration of ROX Reference Dye I and II is 1×. Real-time fluorescence quantitative PCR amplifiers such as LightCycler, Thermal Cycler Dice Real Time System II, and Smart Cycler System do not require the use of ROX Reference Dye.

Определение деятельности:

Using activated mahi-mahi sperm DNA as template/primer, the activity is defined as 1 unit (ты) of acid-insoluble material incorporated, by taking up 10 nmol of nucleotides within 30 minutes at 74°C.

Контроль качества:

This product has undergone quality testing and is free from deoxyribonuclease endonuclease activity, deoxyribonuclease exonuclease activity, и загрязнение рибонуклеазой. Host genomic DNA residual content is below 10 копии.

Product Uses:

Real-time fluorescence quantitative singleplex or multiplex (2-4 каналы) кПЦР (probe method) amplification of DNA or cDNA; absolute quantification qPCR.

Инструкции по использованию:

• Equilibrate the required reagents at room temperature until fully dissolved, gently mix well (do not vortex), use after a brief centrifugation to prevent excessive bubble formation, and avoid repeated freeze-thaw cycles. If used frequently, store at 4°C. Prepare the PCR reaction mixture according to the components listed below (prepare the reaction mixture on an ice box):

Примечание：Количество каждого компонента в реакционной системе может быть скорректировано в соответствии с фактическими требованиями. Users need to decide whether to add ROX Reference Dye based on the actual model being used.

• In general, Двухэтапный метод может быть использован для реакции; if the two-step amplification is not satisfactory, a three-step method can be used to set up the PCR reaction program.

Примечание: Условия реакции могут быть скорректированы и оптимизированы в соответствии с фактическими требованиями.

• After the reaction is complete, analyze the experimental results. For detailed analysis methods, refer to the PCR amplification instrument operating manual.

Меры предосторожности:

1. The concentration of the primers used can be adjusted within the range of 0.2-1.0 мкМ, and the DNA template can be appropriately adjusted based on its concentration.
2. Choose an appropriate annealing (расширение) temperature based on the primer design. Обычно, the Tm value of the primers is designed to be around 60°C. For primers with lower annealing temperatures or for amplifying long fragments exceeding 200 б.п., a three-step method is recommended.
3. The concentration of the probe used can be optimized within the range of 0.1-0.4 мкМ. Conduct experiments with gradient concentrations to find the optimal combination of primers and probes. The use of probes depends on the Real Time PCR instrument, probe type, and fluorescent label type. Refer to the instrument manual or specific requirements for each fluorescent probe for adjustments.
4. Use dedicated areas and pipettors before and after amplification, Носите перчатки, и менять их часто. После ПЦР-амплификации, do not open the reaction tubes directly. Place them at 4°C or -20°C to cool sufficiently before opening to minimize the risk of PCR product contamination in the experimental environment.
