  • 1. Technical Note ® TM Applied Biosystems ViiA 7 Real-Time PCR Run Setup Instructions for qBiomarker Mutation PCR Arrays Before the Experiment  Please make sure the real-time PCR instrument is working properly. Refer to the manufacturer’s Installation and Maintenance manual if needed. Creation of PCR Protocol Template 1) 2) 3) Open the ViiA 7 v1.1 software on the desktop of the computer that is connected to the ViiA 7 instrument. Select File  New Experiment  Experiment. Under Setup  Experimental Properties menu (See Figure 1) a) Select 384-Well Block. b) Select Standard Curve. c) Select TaqMan Reagents. d) Select Standard. Figure 1: Experimental Properties 4) 5) Under Setup  Define menu a) In Define Targets and Samples tab, ensure that FAM is listed beside Target 1. For Quencher, select “none”. Under Setup  Assign menu a) Highlight the entire plate in the Plate Layout window. b) Check the box next to Target 1 under Targets and verify that all wells in Plate Layout view have the “U” symbol (“U” = unknown).

  • 2. Technical Note 6) Under Setup  Run Method menu (See Figure 2). a) Enter 10 µL for Reaction Volume Per Well b) Adjust parameters to reflect the following  Holding Stage  Temperature: 95°C  Time: 10:00  Cycling Stage  Number of Cycles: 40  Step 1: 94°C, 00:15  Step 2: 60°C, 01:00 Detect and record FAM fluorescence from every well during the annealing step of each cycle. 7) Figure 2: Run method Select File Save As Template. Save the file as Experimental Template files (*.edt) with the filename “qBiomarker_Mutation_PCR_Array_Template” (click Save). Performing Real-Time PCR Detection 1) 2) If the thermocycler is off, press the power button to switch on the instrument. Wait for the instrument to boot and display the Power status light. Switch on the computer connected to the thermocycler. Ensure that the plate has been centrifuged for 1 min at 1000 g to remove any bubbles.

  • 3. Technical Note 3) 4) 5) 6) 7) 8) Open the tray and place the plate in the precision plate holder with the last row (row H) facing front. Make sure the plate is properly aligned in the holder, well A1 should be positioned at the top-left corner of the tray. To close the tray door, press the tray to move it into the instrument while applying pressure to the right side of the tray at an angle. Open the ViiA 7 v1.1 software. Select File  New Experiment  From Template. Select the qBiomarker_Mutation_PCR_Array_Template file and click Open. Very that run method is correct. Select Run Menu. Click Start Run in Run Status window. After the PCR Run 1) 2) To determine CT values, Set Baseline at 5 to 18 cycles and Threshold setting at 0.1. Export CT values.
