Description:

MaxDirect Plus RT-PCR Master Mix is capable to detect SARS-CoV2 directly from samples. The RNA Extraction Kit is NOT needed anymore. MaxDirect Plus RT-PCRs works directly from RNA templates.

Storage:

Componentes
MaxDirect Plus Plus RT-PCR 2x Probe Master Mix -25 °C and -15 °C
10x S-CoV2 Duplex Assay -25 °C and -15 °C
S-CoV2 positive control -25 °C and -15 °C
Direct Booster solution 4 and 12 °C

 

Shipping temperature:

Although this Master Mix is stable at +20°C for up to 9 days (if not opened).  We strongly recommend using 2kg. of ice packs to keep the Master Mix in optimal conditions (no heavy dry ice needed).

MaxDirect Plus RT-PCR Probe 2x Master Mix will not lose activity within 10 freeze-thaw-cycles. Additional freeze-thaw cycles could affect the Master Mix’s performance. Keep the kit out from lighting environments.

 

Kit Components:

Component Content Volume
MaxDirect Plus Plus RT-PCR 2x Probe Master Mix DNA Polimerase, dNTP, buffer, PCR additives 1,5 ml

 

10x S-CoV2 Duplex Assay Primer/Probe Mix for SARS-CoV-2 N-gen and RNaseP 300 µl
S-CoV2 positive control DNA Plasmid with target region for SARS-CoV-2 and target region for RNaseP 70 µl
Direct Booster solution Additives that improve the sensitivity of PCR Direct 100 µl

 

PCR Set Up For ALL Sample Collection Methods:

Step Temperature Duration Cycles
Reverse Transcriptase 70 °C 10 min. 1
Denaturation 95 °C 5 seg. 45
Annealing 65 °C 20 seg.*
  • Fluorescence measurement in FAM and Cy5-channel

Thaw kit components on ice, then mix and centrifuge all components.

For the preparation of the PCR Master Mix, the number of total reactions, including positive and negative controls, is calculated. It is recommended to prepare an additional reaction to compensate for the loss of pipetting. Mix and centrifuge the components.

 

1st. OPTION (DRY SWAB based sample collection)

MaxDirect Plus RT-PCR Amplification                    Protocol

Put the dry swab stick thoroughly in 350 µl RNase-free water. Remove debris from the swab by short centrifugation. Then heat the samples for 5 min at 95 °C. The assay detects SARS-CoV2 N1-gene (FAM- channel) and human RNaseP-gene (Cy5-channel).

 

Assay setup

Reagente Volumen
MaxDirect Plus Plus RT-PCR 2x Master Mix 15 µl
10x Duplex Assay 3 µl
PCR-Clean wáter 5.1 µl
Direct Booster solution 0.9 µl
Dry swab RNA sample/positive control/negative control 6 µl
Total 30 µl

The positive control can be used directly or diluted 1 to 10, which will give a solid signal.

 

2nd.OPTION(GARGLE based sample collection)MaxDirect Plus RT-PCR amplification protocol.

Gargle with 5 ml of Clean Water for PCR or 0.9% saline solution for at least 20 seconds and then spit into a PCR tube.

Gargle specimens can be inactivated by heating the tube for 3 min at 95 ° C, the heat inactivated gargle solution can be stored for a maximum of 3 hours at 0-12 ° C before use. But application is recommended immediately after heat inactivation. Take proper precautions against aerosol formation during the gargling process.

Note.- Make sure the patient does not eat, drink, chew gum, or smoke for at least 30 minutes before collecting the sample.

 

Assay setup for Gargle based collection samples:

Content Volumen
MaxDirect Plus Plus RT-PCR 2x Master Mix 15 µl
10X Duplex Assay 3 µl
PCR-Clean Water (Agua de PCR) 5.1 µl
Direct Booster Solution 0.9 µl
Gargling solution/positive control/negative control 6 µl
Total 30 µl

 

3rd.OPTION (RNA Extraction based method)

MaxDirect Plus RT-PCR Master Mix Protocol for extracted/purified RNA samples

Follow the instruction of your RNA extraction kit to process the samples.

The assay detects SARS-CoV2 N1-gene (FAM-channel) and human RNaseP-gene (Cy5-channel).

 

    Assay setup 

Reagent Volume
MaxDirect Plus Plus RT-PCR 2x Master Mix 10 µl
10X Duplex Assay    2 µl
PCR-Clean water    3 µl
RNA extracted sample    5 µl
Total 20 µl

 

Interpretation of data

FAM – N1 Cy5 – RNaseP Interpretation
+ Unclear, repeat experiment
+ + Valid – SARS-CoV2 positive
+ Valid – SARS-CoV2 negative
Invalid, repeat experiment

 

General considerations

  • Use sterile, DNA/DNase/RNase-clean consumables to avoid contaminations.
  • Clean all surfaces and equipment in direct environment before starting the experiment to lower the risk of nucleic acid-, DNase/RNase- and protease contaminations.
  • Do not use this product after its expiry date.
  • Include positive and negative controls in your experiment to validate your results.
