StepOne™and StepOnePlus™ Real-Time PCR Systems Support – Getting Started

The RNaseP verification plate contains template, master mix, and a TaqMan® assay for RNaseP. It is used to verify that the instrument is performing to specifications. If you have reason to suspect there is something wrong with the instrument, or if you want to rule out a chemistry issue, the RNaseP plate is a good way to test the system. It is also recommended to use after the instrument has been moved to a new location. The RNaseP verification plate is a single-use plate.

The calibration plates can be stored and reused three times for up to one year after you receive them, so make sure to return them to their original packaging and return them to –20°C storage until the next use. If needed, you can make your own background plate using deionized water. Please follow the directions in the StepOne™ and StepOnePlus™ Maintenance and Administration Guide (Appendix C) for more details.

Follow these instructions for proper loading of tubes, tube strips, and plates.

• Put the tubes or tube strips in the tray with the adapter on the 96-well support base.
• If using a plate, put the plate directly on the 96-well support base.
• Pipet your reactions into the tubes/tube strips or the wells on the plate.
• Seal the tube/tube strips with optical flat caps.
• If using a plate, seal the plate with either optical adhesive film or flat caps.

For optimal performance on the StepOnePlus™ instrument with partial loads:

• Load at least 16 tubes and arrange them in adjacent columns of 8 tubes, using rows A through H, or adjacent rows of 8 tubes, using columns 3 through 10.

For optimal performance on the StepOne™ instrument, load at least 4 tubes in the sample block.

Please refer to this selection table for compatible plates, tubes, and films.

The StepOnePlus™ Real-Time PCR System contains six independently thermally regulated VeriFlex™ blocks, which can help you optimize your thermal cycling conditions. You can set a different temperature for one or more zones, or you can set one temperature for all zones in the sample blocks. [Note: The difference in temperature between adjacent zones can range from 0 to 5°C, in 0.1°C increments].

1. Choose ‘New Experiment’ → ‘Advanced Setup’ and choose the Experimental Properties as normal.
2. Under ‘Plate Setup’ → ‘Assign Targets and Samples’
3. On the right-hand side under ‘View Plate Layout’, check the box to ‘Enable VeriFlex™ Block’, and click ‘Yes’ to the box. You should now see the plate separated into 6 zones by red lines.
   
4. Click on ‘Run Method’ in the left-hand column. On the Graphical View, click on the temperature that you want to change. A new window will pop up. Choose ‘Set different temperatures for one or more zones’. Adjust the temperature as needed for each zone.
   
5. After you click ‘OK’ you will see the ‘Zones’ represented on the thermal profile. If you hover over the word ‘Zones’, you can see the temperatures you set.
   

In a touchdown PCR experiment, you will change either the temperature or the time of a particular PCR step with every cycle. Most commonly, the annealing temperature is adjusted throughout the experiment, such that the specificity is higher in the early cycles and the efficiency in the later cycles. In this example, we will set the method to do the following:

40 cycles

95°C, 20 sec 95°C, 3 sec 72°C, 30 sec (decreasing by 0.4°C every cycle, starting at cycle 2)

1. Go to File → New Experiment → Advanced Setup. Fill out the relevant options as you normally would.
2. Go to the Run Method under the ‘Setup’ section and you should see the Graphical View of your thermal profile. Check the box next to ‘Enable AutoDelta’. You should see some grey triangles appear next to the Temperature and Time at every step in the Cycling Stage. (Note: If you want to start the changes at a later cycle, set this here under ‘Starting Cycles’.)
   
3. A new window called ‘AutoDelta Settings’ will open up. Select the appropriate options. In this example we are decreasing the temperature by 0.4°C per cycle, so choose (“-“) and (0.40). Click ‘Save Setting’. You will then see a green triangle show up next to the parameter you changed, in this case next to the 72°C step. Your new method has now been applied.
