Electrophoresis
4.1 Pre-electrophoresis
1. Remove the gel sealing tape from the bottom of the gel sandwich, if tape was used. Rest the
bottom edge of the sandwich on the footing in the lower reservoir, notched plate inward. Using
mounting clamps (cat. # GPC-0001) attach the lower section of the glass plate assembly to
the upright of the sequencer. Do not clamp glass plate assembly to the upper reservoir until
the sharktooth comb is inserted.
2. If you are using a sharktooth comb, insert the comb (teeth-down) between the glass plates.
Insert the comb until the teeth just make contact with the surface of the gel. Do NOT allow
the teeth to pierce the gel. A very slight indentation of the gel should be visible when the
comb is properly inserted. Do not slide the comb laterally after it has come in contact with the
gel.
3. Slide the upper reservoir to the glass plate sandwich and clamp using the bar clamp. Pre-
loosen black wing nuts so clamp assembly slides over glass plates and upper reservoir,
without disturbing the comb. Tighten wing nuts only enough to compress gasket. Do NOT
over tighten. See figures below.
