PRODUCT INFORMATION
Description

2X premix reagent optimized for dye-based Real-time PCR with enhanced amplification kinetics and superior sensitivity.

    • Contains next-generation antibody-mediated Taq DNA Polymerase, ultrapure dNTPs, MgCl₂, and proprietary specificity-enhancing factors
    • Requires only primers and template DNA for immediate qPCR setup
    • Pre-mixed Universal ROX enables compatibility with Low-ROX, High-ROX, and ROX-independent instruments
    • Built-in blue tracking dye allows visual verification of pipetting accuracy and reduces handling errors
    • Dual-action enzyme system suppresses primer-dimer formation for highly reproducible results
    • Enables linear detection down to single-digit template copies with high sensitivity (R²=0.9994)

RealMOD™ Green T² 2X qPCR mix is a premixed reagent specifically designed for dye-based Real-time PCR applications by maximizing DNA amplification kinetics. This product contains all essential components required for qPCR, including a next-generation antibody-mediated Taq DNA Polymerase, ultrapure dNTPs, MgCl₂, and proprietary specificity-enhancing factors, requiring only the addition of primers and template DNA. The inclusion of a Universal ROX reference dye ensures seamless compatibility across various qPCR platforms without the need for calibration. In addition, a non-interfering blue tracking dye provides real-time visual confirmation during pipetting, reducing human error. The advanced dual-action enzyme system suppresses non-specific amplification and ensures highly reproducible detection.

Technical Data

Maximize Dynamic Range & Signal Intensity

RealMOD™ Green T² 2X qPCR mix is engineered to deliver sharp, high-plateau amplification curves and absolute quantitative accuracy across any DNA concentration, from bulk genomic DNA to low-copy cDNA libraries.


 

Performance Comparison against Competitor (GAPDH Target)


​ Assay Profile: Comparative quantification of a standard housekeeping gene target from human genomic DNA template.

​ Dilution Matrix Parameters: The DNA template was 10-fold serially diluted from 5 ng down to50 pg (executed in duplicate).

​ Performance Validation: RealMOD™ Green T² 2X qPCR mix (Green curves) demonstrates significantly earlier Ct values, substantially higher final fluorescence intensities (Plateau values), and a highly specific single-target amplification profile compared to Supplier A (Blue curves).

 

 

Linear Dynamic Range for Low-Copy DNA Targets (CPIV cDNA)


​ Verification Matrix: Validation of a broad linear dynamic range and high-sensitivity quantification infrastructure utilizing a 10-fold serially diluted DNA template (ranging from high concentration down to single-digit copy thresholds) executed in duplicate amplification kinetics.

​ Experimental Assay Criteria: Dynamic range amplification curves of the targeted DNA region.

​ Performance Validation: The precisely and evenly spaced amplification curves demonstrate excellent, near-perfect amplification efficiency and highly robust detection capabilities even at ultra-low DNA concentration thresholds. This confirms the kit's broad template compatibility and exceptional performance stability with challenging, low-copy DNA types.

TroubleShooting Guide
Q
Why am I seeing multiple peaks in my melting curve or experiencing low target specificity?
A
This is typically caused by inappropriate primer design or concentration. We recommend redesigning primers according to standard principles or decreasing the primer concentration if it is too high. You may also try increasing the annealing temperature by 1–2°C. Additionally, ensure the cDNA template is not contaminated with genomic DNA; if contamination is suspected, prepare new cDNA templates.
Q
What should be done if amplification is observed in the Negative Control (NTC)?
A
This indicates either contamination of the reaction system or the formation of primer dimers. Replace the master mix, nuclease-free water (ddH₂O), and primers with fresh stocks and repeat the experiment. To minimize aerosol contamination, it is critical to prepare the reaction system in a clean bench. Use a melting curve analysis to confirm if primer dimers are the cause.
Q
How can I resolve poor experiment repeatability or a non-linear standard curve?
A
These issues are frequently caused by pipetting volume deviations, low template concentrations, or instrument temperature variances. Use high-performance pipettes and increase both the template dilution factor and the pipetting volume to minimize errors. If template concentration is low, repeatability worsens; reduce the dilution factor or increase the volume of the sample added. Finally, ensure the qPCR instrument is regularly calibrated for uniform temperature across all wells.
Q
What are the primary causes for a lack of an amplification curve or significantly delayed Ct values?
A
Ensure that the number of cycles is set to 40 and that the signal acquisition step is correctly programmed for the annealing/extension stage. If the template is degraded or contains inhibitors, prepare a new one. Verify primer integrity and ensure PCR product lengths are between 80–150 bp. If custom primers fail at 60°C, optimize the annealing temperature down to 55°C.
Q
Why does my amplification plot have an abnormal, "broken," or rough shape?
A
Ambient air bubbles in the reaction tube often interfere with optical results; ensure thorough centrifugation before the run. If the plot appears broken or downward, the template concentration may be too high—manually reduce the baseline endpoint to (Ct value - 4). If the plot is rough or jagged, the signal may be too weak, requiring an increase in template concentration.
