      INNOVATION IN REAL-TIME PCR
       
      Leading edge assays with proprietary technology
       
      ELITe MGB™ is a revolutionary advance in Real-Time PCR chemistry. All ELITe MGB™ assays have been designed with our proprietary Minor Groove Binder (MGB) protein, Superbases™ and Eclipse®Dark Quencher technologies.

    Our patented technology features shorter, overlapping probes that efficiently and accurately detect target DNA sequences, while offering greater sensitivity and specificity.

    The MGB protein is a synthetic molecule that binds to the minor groove of double stranded DNA molecules. In Real-Time PCR applications, MGB increases the stability of double stranded DNA complexes, specifically, the hybridization between the probe and the amplified DNA target. The increased DNA-DNA hybrid stability allows the design of shorter detection probes with higher specificity. Furthermore, the specificity of ELITe MGB™ probes increases the ability to discriminate between a perfectly matched sequence and a mismatched target compared to analogous MGB-free, longer counterpart probes.
       
      Superbases™ are specially engineered, nitrogen-based nucleotides. The proprietary design of these nucleotides minimizes secondary and tertiary structure observed in A-T or G-C rich DNA target sequences. This feature allows ELITe MGB™ assays to target even the most challenging gene sequences without compromising accuracy, clinical specificity or sensitivity.

    The Eclipse®Dark Quencher is a proprietary fluorophore and dye quencher chemistry resulting in low background signals. Its key benefit is to ensure that every ELITe MGB™ assay will have the highest sensitivity by minimizing background signal interference.
       
      ELITe MGBprobes feature higher sensitivity, specificity and low fluorescence background.
       
      Universal Cycling Conditions
       
      All the ELITe MGBTM assays utilize the same temperature and amplification profile. Known commonly as Universal Cycling Conditions, this profile consists of a three-step protocol: a denaturing step, an annealing step and an extension step. Universal Cycling Conditions enable laboratories to create multiple targets runs that can be run simultaneously on the same thermocycler.

    Denaturation step: The coiled ELITe MGBTM probe float freely in solution and will not emit fluorescence due to the close proximity of the fluorophore and dye-quencher.

    Annealing step: The probe anneals to the target DNA sequence. In this conformation the fluorophore is separated from the quencher and emits light at a specific wavelength.

    Extension step: During DNA polymerization, the probe is displaced from the target gene sequence and reverts to its coiled-conformational state without being hydrolyzed. In this state, the probe is free in solution and will not emit fluorescence due to the close proximity of the fluorophore and dye-quencher.
       
      Monoreagent format
       
      ELITe MGB™ mastermix has been reformulated to allow for a larger sample volume, significantly improving assay sensitivity. ELITe MGB™ mastermix is provided as a single solution in a ready-to-use format and includes all the components required for Real-Time PCR. No pipetting, mixing or reagent set-up is necessary; simply aliquot mastermix into the reaction wells and add your extracted sample.
       
      Melt-curve analysis
      The melt-curve analysis is a technique that monitors the relative fluorescence from the ELITe MGB™ probe as the temperature is gradually increased. This process creates a sequence specific dissociation profile, or melt-curve fingerprint, that is unique for a given doublestranded DNA fragment. For laboratories to utilize this valuable tool, Real-Time PCR methods must use DNA probes that are intact and undegraded. During Real-Time PCR, ELITe MGB™ Probes remain intact (unlike older Real- Time methods in which probes are degraded).

    At low temperature, ELITe MGB™ probe is hybridized to the DNA target generating maximum fluorescence. Increasing the temperature causes the ELITe MGB™ probe to dissociate or “melt” from the DNA target. As the ELITe MGB™ probe “melts” the fluorophore and quencher are brought back in proximity resulting in lower fluorescence. See upper graph at left.

    Creating a second graphic (first derivative) will identify the specific Melt Temperature (TM) corresponding to the inflection point in the first graphic.

    Because melt-curve analysis can resolve subtle pairing differences between the probe and target sequences, it is a valuable tool to identify clinically relevant DNA sequence alterations. A mismatch pairing could result in an underestimation of the quantity of bacterial or viral target present in the clinical sample. By analyzing the melt-curve profile at the end of each amplification, the accuracy, specificity and integrity of the quantitative analysis can be assessed.

    As such, melt-curve analysis gives clinicians critical data that could be clinically or therapeutically important or impact the course of care for their patients.
