Real-time fluorescence Quantitative qPCR (Dye Method) amplifies DNA or cDNA; Absolute Quantitative qPCR; Relative Quantitative qPCR.

Instructions for Use:

• Allow the required reagents to equilibrate to room temperature until completely dissolved, gently mix thoroughly (do not vortex), use after brief centrifugation to avoid excessive bubble formation and repeated freeze-thaw cycles. If used frequently, store at 4°C. Prepare the PCR reaction mix according to the components pressed down (prepare the reaction mix on an ice box):

Catatan：The amounts of each component can be adjusted according to actual needs. The addition of ROX Reference Dye should be determined by users based on the specific model being used.

• In general, metode dua langkah dapat digunakan untuk reaksi. If amplification is not satisfactory with the two-step method, metode tiga langkah dapat digunakan untuk menyiapkan program reaksi PCR.

Catatan： The reaction conditions can be adjusted and optimized according to actual needs. The melting curve program should be selected and adapted based on the amplification instrument’s program being used.

• After the reaction is complete, analyze the amplification curve and melting curve results. Refer to the Real-Time PCR instrument’s user manual for detailed analysis methods.

Tindakan pencegahan:

1. Please select appropriate annealing (perpanjangan) temperatures based on primer design, with the primer Tm typically around 60°C. For primers with lower annealing temperatures, a three-step method is recommended. The final concentration of used primers can be adjusted within the range of 0.2-1.0μM. The DNA template concentration can be adjusted according to its concentration.
2. SYBR Green I dye is a non-specific dye that emits fluorescence upon binding to double-stranded DNA (dsDNA). Namun, it is easily degraded under strong light. Karena itu, when designing primers, it is important to avoid primer dimer formation as much as possible. During usage, prolonged exposure to strong light should be avoided to enhance result accuracy, sensitivity, and specificity.
3. Increasing the magnesium ion concentration can reduce the inhibitory effect of SYBR Green I on PCR reactions. When optimizing fluorescence PCR reactions using this product, it is advisable to slightly increase the magnesium ion concentration (0.5-3.0mM higher than standard PCR reactions).
4. Use dedicated areas and pipettes before and after amplification, memakai sarung tangan, dan sering-seringlah mengubahnya. Setelah selesai reaksi PCR, do not open the reaction tubes to minimize contamination of the testing environment with PCR products.
