Positioning the Gel
To position a gel
1. Center the gel on the sample area.
Note: Ensure that the calibration area is clean and free of any dust or
droplets. Contamination can affect the calibration, and therefore the
results.
2. Lower the lid.
3. Set up a protocol or use an existing protocol.
4. Click Preview Gel.
The densitometer quickly scans the sample gel. Based on the protocol settings,
Image Lab displays the results of the scan in a scan area box outlined in red as
the scan progresses.
Tip: If you determine that the settings are incorrect during the preview
scan (the sample of interest is not in the red box), click Cancel Run. Image
Lab returns to the Protocol Setup window where you can reset the scan
image coordinates.
