Notes
Figure 11. Primer/Probe Tab displaying candidate primers and probes
Evaluating the candidate primer and probe sets:
The Location section illustrates the location of the primers and probes within the line
sequence. The number above the line is the starting base; the number below the line is
the ending base. Note that you can also see the corresponding location of a selected
candidate Primer/Probe set in the Sequence tab.
In the sequence tab, the probe 1 will be highlighted in pink, probe 2 will be highlighted
in green (if probe 1 and 2 overlap, the overlap region will appear green), the forward
primer in blue, and the reverse primer in yellow (see “Figure 12. Probe annotations in
Sequence tab” on page 33). These default color designations can be changed by clicking
Tools > Opt ions. If you place your cursor over any of these annotations, a tool tip will
appear showing the name of the annotation (Probe, Forward Primer, Reverse Primers)
start and end locations, Tm and GC%.
