Figure 18 Effect of bubbles at the gel interface on TapeStation Analysis software results
- Gel view/unaligned
Air bubbles present at the top of the buffer chamber are normal and
acceptable.
The presence of small bubbles within the buffer chamber of the ScreenTape devices is
normal and acceptable. These bubbles often occur at the gel/buffer interface and need to
be displaced prior to running. Failure to remove bubbles from the gel/buffer interface is
detrimental to the performance of the ScreenTape assay.
ScreenTape devices have an expiration date. If a ScreenTape device beyond the expiration
date is used, a message will show up in the TapeStation Controller software interface.
Starting a sample analysis with an expired ScreenTape device is not allowed by the
software. Assay performance specifications do not apply beyond the expiration date.
Changing TapeStation Controller software settings will permit the instrument running
expired ScreenTape devices, see “TapeStation Controller Software Settings” on page 55.
Resulting data are marked accordingly.
