Troubleshooting
The table below provides some solutions to possible problems you might
encounter during the electrophoresis of E-PAGE
™
Gels. For issues with protein
transfer, refer to the manual for the iBlot
®
Gel Transfer Device.
Observation
Cause
Solution
No current
Daughter E-Base
™
Device used
without a Mother E-Base
™
Device
Do not use the Daughter E-Base
™
Device
without a Mother E-Base
™
Device. The
Daughter E-Base
™
Device does not have an
electrical plug to connect to an electrical
outlet.
No electric contact (no
red light when
cassette is inserted) or
run does not start (no
green light)
Copper contacts in the base are
damaged due to improper use
Make sure that the copper contacts in the base
are intact.
Expired or defective gel cassette
used
Use properly stored gels before the specified
expiration date.
E-PAGE
™
cassette is not
correctly inserted into base
Remove cassette and reinsert. When the
cassette is correctly inserted and power is on,
a fan in the base begins to run and a steady
red light illuminates on the base (page 17).
Sample leaking from
the wells
Sample is overloaded or wells
are damaged
Be sure to load the recommended volume of
sample per well (page 16).
Remove the comb carefully without
damaging the wells.
Poor resolution or
smearing of bands
Sample is overloaded
Do not load more than 20 µg of protein
sample per well.
Very low volumes of sample
were loaded
Do not load less than 5 µL of sample. Always
load 10–20 µL deionized water in all wells
prior to sample loading.
For proper band separation, we recommend
keeping sample volumes uniform and
loading deionized water into empty wells.
Incorrect loading buffer used
Make sure that protein sample is in one of
Use the recommended loading buffers as
described on page 10.
Electrophoresis was not started
immediately after sample
loading
For best results, the gel should be run within
15 minutes of sample loading.
