User Manual

5 Using the forceps, carefully push the strip into the well as shown in Figure 13, taking care

not to trap any air bubbles beneath the strip. When pushing the IPG strips with the for-

ceps be certain the forceps are pushing on the plastic backing to the strip and not the gel

matrix.

6. Stand the gel(s) vertically by placing them in the gel box (Criterion system) or in a test tube

rack. Allow the agarose to solidify for 5 minutes before proceeding.

7. Mount the gel into the gel box per the instructions provided with the apparatus.

8. Fill the reservoirs with 1X Tris/glycine/SDS running buffer and begin the electrophoresis.

Table 4 lists the electrophoresis run conditions for each of Bio-Rad’s three SDS-PAGE for-

mats. The migration of the Bromophenol Blue, present in the overlay agarose solution, is

used to monitor the progress of the electrophoresis.
