For optimal results, white LightCycler® 480 Multiwell plates are recommended.

HybProbe Probes

The LightCycler® Probe Design Software 2.0 can design the best HybProbe probe and primer combinations and give precise estimations of the Tms of the primers and probes in LightCycler® reagents.

Performing a Melting Curve analysis with HybProbe probes can identify and characterize PCR product/probe hybrids using their specific melting behavior for genotyping and mutation analysis.", "Country": "XG", "Code": "Background Information - Help Corner", "Name": "Background Information - Help Corner" }, { "Language": "en", "Value": "The LightCycler® 480 Genotyping Master is function tested using the LightCycler® System.", "Country": "XG", "Code": "Quality Control", "Name": "Quality Control" }, { "Language": "en", "Value": "In principle, the LightCycler® 480 Genotyping Master can be used to amplify and detect any DNA target. However, you would need to adapt your detection protocol to the reaction conditions of the LightCycler® 480 Instrument, and design specific PCR primers and probes for each target. See the LightCycler® 480 Operator’s Manual for general recommendations.
The amplicon size should not exceed 700 bp in length. For optimal results, select a product length of 100 to 500 bp for monoplex and ≤350 bp for multiplex assays.
The performance of the kit described in this Instructions for Use is warranted only when it is used with the LightCycler® 480 System.
Detection formats
You can use this kit for both the HybProbe and SimpleProbe detection format.
Use a 1:5 dilution of the LightCycler® 480 Genotyping Master to prepare the PCR Mix for HybProbe probes. The MgCl2 concentration in this mix gives optimal results with nearly all primer combinations.
Use a 1:10 dilution of the LightCycler® 480 Genotyping Master to prepare the PCR Mix for SimpleProbe probes. For this type of analysis, it might be helpful to add additional MgCl2 (Vial 3). Melting curve results will improve if you dilute the mix even further, for example, using a 1:20 dilution. If you dilute the mix further, you must also add additional MgCl2 to the reaction. The final concentration must be 3 mM, therefore, add an extra 1.8 μl MgCl2 from Vial 3 if you dilute 1:20.

Two-Step RT-PCR
LightCycler® 480 Genotyping Master can also be used to perform two-step RT-PCR. In two-step RT-PCR, the first step, reverse transcription of RNA into cDNA, is performed outside the LightCycler® 480 System. Subsequent amplification and online monitoring is performed according to the standard LightCycler® 480 System procedure, using cDNA as starting sample material.
One of the following reagents is required for reverse transcription of RNA into cDNA (see Ordering Information section for details):
  • Transcriptor Reverse Transcriptase*
  • Transcriptor First Strand cDNA Synthesis Kit*
Synthesis is performed according to the detailed instructions provided with the cDNA synthesis reagent.
For initial experiments, run undiluted, 1:10 diluted, and 1:100 diluted cDNA template in parallel to determine the optimum template amount.

For reproducible isolation of nucleic acids, use:
  • Either a MagNA Pure System together with a dedicated reagent kit (for automated isolation),
  • or a High Pure Nucleic Acid Isolation kit (for manual isolation).
  • Use up to 50 ng complex genomic DNA or 1 to 108 copies plasmid DNA for a 20 μl reaction. For larger volumes, the amount of template can be increased equivalently.
When using unpurified cDNA from a reverse transcription reaction, especially when it contains high concentrations of RNA and oligonucleotides, you can improve your results by using 2 μl (or less) of that sample in the reaction.

The LightCycler® 480 Genotyping Master is a ready-to-use hot start reaction mix designed specifically for genotyping (SNP analysis with melting curves). It is optimized for use with HybProbe probes but can also be used with SimpleProbe probes.

    The kit can also help prevent carryover contamination during PCR when used with LightCycler® Uracil-DNA Glycosylase or to perform the second step of a two-step RT-PCR.", "Country": "XG", "Code": "Applications", "Name": "Applications" }, { "Language": "en", "Value": "HybProbe probes consist of two different oligonucleotides that hybridize to an internal sequence of the amplified fragment during the annealing phase of PCR cycles. One probe is labeled at the 5' end with a suitable acceptor fluorophore (LightCycler® Red 610, LightCycler® Red 640, or Cy5), and to avoid extension, modified at the 3' end by phosphorylation. The second probe is labeled at the 3' end with the donor dye fluorescein (Fluos). Only after hybridization, the two probes are in close proximity, resulting in fluorescence resonance energy transfer (FRET) between the two fluorophores. During FRET, fluorescein, the donor fluorophore, is excited by the light source of the LightCycler® 480 Instrument, and part of the excitation energy is transferred to LightCycler® Red, the acceptor fluorophore. The emitted fluorescence of the acceptor fluorophore is measured.  LightCycler® Red 610, LightCycler® Red 640, or Cy5-labeled HybProbe probes can be used separately or in combination, therefore allowing single- or multiple-color detection. Refer to the LightCycler® 480 Operator`s Manual for additional information.

    The SimpleProbe format uses only one oligonucleotide probe. This single probe is designed to specifically hybridize to a target sequence that contains the SNP of interest. Once hybridized, the SimpleProbe probe emits much more fluorescence than it does when it is not hybridized. As a result, fluorescent signal changes are based solely on the hybridization status of the probe. SimpleProbe assays can distinguish between wild type, mutant, and heterozygous samples.

    The LightCycler® 480 Genotyping Master is a ready-to-use reaction mix designed for the HybProbe probe detection format and SimpleProbe probe detection format using the LightCycler® 480 System. It is used to perform hot start PCR in LightCycler® 480 Multiwell Plates.
    Hot start PCR has been shown to significantly improve the specificity and sensitivity of PCR (Chou, Q., et al., 1992, Kellogg D. E., et al., 1994, Birch, D. E., 1996) by minimizing the formation of nonspecific amplification products at the beginning of the reaction.
    The polymerase in this master is a 5'-3'-exo-minus, N-terminal deletion of  thermostable recombinant Taq DNA polymerase and furthermore, is chemically modified. It shows no activity up to 75°C because of the heat-labile blocking groups on some of the amino acid residues of the enzyme. Therefore, there is no elongation during nonspecific primer binding. The modified enzyme is “activated” by removing the blocking groups at a high temperature (that is, pre-incubation at 95°C for a maximum of 10 minutes).
    The LightCycler® 480 Genotyping Master provides convenience, excellent performance, reproducibility, and minimal contamination risk. All you have to supply is template DNA, PCR primers, HybProbe or SimpleProbe probes, and additional MgCl2 (if necessary).", "Country": "XG", "Code": "Principle", "Name": "Principle" }, { "Language": "en", "Value": "Always run a negative control with the samples. To prepare a negative control:
    • Replace the template DNA with Water, PCR Grade (Vial 2). This will reveal whether a contamination problem exists.
    • For a 2-step RT-PCR setup, omit the addition of reverse transcriptase to the cDNA synthesis reaction; this will indicate whether DNA in RNA samples causes false-positive results.

The supplied enzyme contains a 5'-3'-exo-minus, N-terminal deletion of thermostable recombinant Taq DNA polymerase that is inactive at room temperature due to a chemical modification, and becomes activated during a 10-minute incubation at +95°C. HybProbe probes or SimpleProbe probes are used as detection format during PCR and subsequent melting curve analysis.

    Since the mix is provided as a one-component, easy-to-use reagent, reaction setup only requires the addition of template DNA and primers. The mix can be used with different types of DNA (e.g., genomic, cDNA), and is ideally suited for high-throughput applications in 96- or 384-well plates.", "Country": "XG", "Code": "Product Description", "Name": "Product Description" } ] } } ] }
