4.2 Changing the Fluorescence Intensity Scale
To display more or less detail in the electropherogram traces and lanes in the virtual gel, use the options
available under the Graph menu. These options determine the y-axis scale (fluorescence intensity) of
electropherograms and define the relative scale intensity of the lanes in the virtual gel (Figure 4.10):
n
Scale To Selected — uses the fluorescence value of the tallest peak in a selected
electropherogram to set the scale of the y-axis for all samples. Use this option when
comparing (overlaying) a sample with a high-intensity peak and one with a less intense
peak
n
Scale To Global — uses the fluorescence value of the tallest peak from all the samples to
set the scale of the y-axis for all samples. Use this option to create a virtual gel similar to an
agarose gel
n
Scale To Local (default) — uses the fluorescence value of the tallest peak in each
electropherogram to set the scale of the y-axis for that electropherogram: each sample is
scaled separately. This is the best way to view electropherograms and sample details
n
Scale To Selected Peak — uses the fluorescence value of the selected peak to set the
scale of the y-axis for all samples
Fig . 4 .10 . Options for modifying the fluorescence intensity scale . Examples of how each option affects the display of a virtual gel are shown.
