O. Air dry or use a lint-free tissue. Spray/wipe the chosen inner surfaces of the plate set
with 95% ethanol and dry with lint-free tissue.
3.3 Gel Casting Techniques.
A. Gel Wrap™ Gasket Casting Method.
B. Vertical gradient gel casting using GM-40 gradient maker and gravity flow.
C. Vertical gradient gel casting using GM-40 gradient maker and a Mini-pump.
D. Vertical gradient gel casting using GM-40 gradient maker, Mini-pump and Multi-gel
Caster.
NOTE:
Prior to casting, mark the notched glass plate to designate which side is the ‘inside’ and
‘outside’. The same side of the notched plate should always sit against the reservoir gasket.
A. Gel Casting using Gel Wrap
™
Gasket Casting method
For Vertical DGGE, use the set of spacers which do not have the small hole or channel milled
into the lower end, these are for casting perpendicular gels.
1. Start by holding the rectangular back
plate with the rounded bottom corners
and start applying the gasket around
one side of the glass plate. Note: one
side of the “U” shaped gasket is flat,
and the other side has tubing that will
act as a seal around the spacers.
2. When applying the gasket over the
rounded corners of the back glass plate,
make sure the notches on the gasket
align with the rounded corners of the
glass plate. Once the gasket is pushed
over the bottom edge and corners, work
it down the remaining side.
