Gel Casting into Gel Tray.
1. Tape both ends of gel tray with tape.
2.Position the gel comb(s) in the gel tray. Using
a pipette or a pipetor, run a bead of agarose
solution along the edges of the gel tray where it
meets the tape to assure a leak-proof seal.
Then pour the agarose solution into the gel tray.
Allow the agarose slab to cool uncovered until it
turns opaque. NOTE: (Optional storage) Pre-
cast gels can be stored for up to one month if
wrapped in plastic wrap and stored at 4
°C.
Remove combs prior to storing.
3.Remove gel tape at each end. Position
the
tray in the unit, remembering, current travels
from negative (black cathode) towards positive
(red anode).
