Aladdin's UltraBio™ Multiplex Probe qPCR Mix (2X, UDG) is a new high-quality carryover prevention supermix for probe-based real-time PCR which is also called TaqMan probe-based qPCR when TaqMan probe is used. It is mainly used in gene expression studies and genomics applications, with high specificity and sensitivity. The product contains an optimized ratio of high quality UDG enzyme and dUTP to effectively eliminate false positives or low CT values caused by carryover contamination in PCR. The method utilizing the TaqMan probe is also referred as the Anti-Contamination TaqMan Probe Method.Uracil-DNA Glycosylase (UDG), also known as Uracil-N-glycosylase (UNG), catalyzes the hydrolysis of the N-glycosidic bond between the uracil (dU) base and the deoxyribose moiety in uracil-containing DNA strands, thereby releasing free uracil. Its main application is to eliminate carryover contamination in PCR. The working principle is as follows
Precautions：
PrecautionsPrecautions should be taken to avoid cross-contamination. Discard PCR products after sealing to avoid their contamination of experimental surroundings.This product is for R&D only. Not for drug, household, or other uses.For your safety and health, please wear a lab coat and disposable gloves during the operation.Instructions for Use：
1.Prepare qPCR reactionsa.Thaw and mix well the Multiplex Probe qPCR Mix (2X, UDG). Keep it on ice after thawing until use.b.Assemble the qPCR reaction on ice or at room temperature as follows (e.g., in a 96-well plate):ReagentVolumeFinal Concentration Multiplex Probe qPCR Mix (2X, UDG)10µl1XForward and Reverse Primer Mix (3μM each)2µl300nMProbe0.5µl200nMTemplate DNA2µl 1pg-2µgWithout or Low/High ROX (50X)0.4µl1XRNase-free WaterUp to 20μl-Note 1: Each primer at a final concentration of 0.2-0.5μM normally works well, but the primer concentration can be optimized between 0.1-1.0μM.Note 2: The optimal concentration of the probe is dependent on the type of qPCR instrument, probe, and the fluorophore group. In general, the concentration of the probe should be lower than the primer concentration. For example, if the primer concentration is 0.3μM, the concentration of the probe is recommended to be 0.2μM, which can be adjusted appropriately in the range of 0.1-0.3μM.Note 3: Add 1-10ng of cDNA or 10-100ng of genomic DNA in 20µl of qPCR reaction as a starting point. If necessary, the DNA templates can be diluted in a gradient manner to determine the optimal amount. When the cDNA obtained by RT-PCR reaction is directly used as the template, the addition amount should not exceed 10% of the total volume of the PCR reaction.Note 4: A reaction volume of 20µl is recommended for each well of a 96-well plate, which can be adjusted as needed.Note 5: Negative control without DNA template is always recommended.c.Gently mix the reaction well by vortex or pipetting. Centrifuge briefly to collect the liquid at the bottom of the PCR tube.2.Transfer the qPCR reaction to a qPCR instrument (e.g., ABI QuantStudio™ 6 Flex Real-Time PCR System) and run thermocycling conditions as follows:StepTemperatureDurationCyclesTreatment with UDG Enzyme50ºC5 min1Initial Denaturation95ºC2 min1Denaturation95ºC15 sec35-45Annealing and Extension60ºC15-30 secMelting Curve (optional)95ºC15 sec160ºC15 sec95ºC15 secNote 1: The qPCR running conditions listed above are for general use only. They can be adjusted based on the template, primer sequence, the length of PCR product or GC content, etc. Note 2: The initial denaturation time is usually 2 min, but can be adjusted to 5 min for the amplification of complex or GC-rich DNA fragments.Note 3: The Taq DNA Polymerase is capable of amplifying at least 300bp in 15 seconds. For amplicons longer than 350bp or with high GC content, it is recommended to increase the extension time to 60 s or to use a three-step method to improve amplification efficiency.Note 4: When the annealing temperature of primers is lower than 60ºC, we recommend using the three-step method for PCR amplification (i.e add an extension step at 72ºC for 30 seconds after annealing).FAQ:1.Low specificity or low amplification efficiency.a.Primer sequence is not well designed. Use primer design tools to avoid inappropriate GC content, secondary structure, dimer, annealing temperature, length, specificity and other possible problems.
