E-Gel
™
EX Agarose Gels can be used to run RNA samples. RNA can be run under denaturing or
non-denaturing conditions. Use non-denaturing conditions only when checking for RNA quality,
where accurately determining size is not critical. See page 46 for instructions on performing
electrophoresis of RNA samples.
Opening E-Gel
™
cassettes
•
Electrophoresis must be complete before opening the E-Gel
™
cassette.
•
Photograph the gel before opening the cassette.
•
If you plan to isolate DNA from the E-Gel
™
agarose gel, open the cassette and excise the gel
fragment immediately after electrophoresis as bands will diffuse within 20 minutes.
•
If you plan to blot the gel, prepare your blotting apparatus before opening the cassette.
•
Important!
Before opening the E-Gel
™
cassette, put on safety goggles and gloves.
Gel Knife
The Gel Knife (Cat. no. EI9010) is used to open the cassette for E-Gel
™
EX and E-Gel
™
NGS agarose gels.
Open E-Gel
™
EX and NGS cassettes with a Gel Knife
1.
Place the cassette on a flat surface, with the
wells facing upward.
2.
Insert
the sharp edge of the gel knife into the
groove around the edge of the cassette edge,
then lever the knife up and down to crack the
seal.
3.
Unseal
the plate by working around the
perimeter of the entire cassette and cracking
the seal for every edge.
4.
Remove the top of the gel cassette after all
four sides of the cassette are unsealed.
5.
Proceed to downstream application.
If you plan to transfer DNA from the gel by
blotting, only the main running gel is
required. Remove the upper and lower ion
exchange matrix layers and the well areas
with the Gel Knife.
If you plan to purify DNA from the gel,
excise the gel fragment. Transfer the gel slice
to a microcentrifuge tube.
