• Once the experiment is initiated xxpress performs a number of
checks on the plate and initialises it systems. There will then be a
short whirring sound as it clamps the plate into the unit before it
starts the heat cycling.
• Once the measurement cycles are running the results will appear
on the chart, the chart can be zoomed by gestures as described
earlier. The chart data can also be adjusted selecting the filters on
the right, touch the tiles to toggle these filters on and off.
 BASELINE SUBTRACT uses the early readings to set the initial
level of the trace at zero to make it easier to compare
multiple traces.
 SMOOTH creates a best fit curve to the data which helps in
comparing the results.
 COLOUR COMPENSATION is used for multiplex assays and
reduces the effects of cross-talk from adjacent channels. It is
not required for a single channel experiment. (See notes on
Colour Compensation)
• Once all the cycles are complete xxpress will display a measure
confirming that the experiment is complete, see Figure 9a. Touch
the tick to accept this, the results are saved automatically and can
now be analysed or export (see Section 7.2.5).
