1. Assemble vertical slab gel apparatus using 1mm spacer.
Tip:-the plate should be thoroughly cleaned and dried
before use.
2. Seal the glass plates on 3 sides with 1% agarose.
3. Pour the separating gel/ resolving gel mixture to a level
of approximately 2.5 cm below the glass plates, gently
layer 250μl of TDW over the gel surface. Allow to
polymerize.
Tips: prepare the solution freshly each time it is
required. As soon as ammonium persulphate is added,
the gel should be poured quickly before the acrylamide
polymerizes.
4. After polymerization remove water from the top.
5. Pour the prepared 5% stacking gel over the resolving
gel/ separating gel.
6. Immediately insert a comb and allow polymerizing the
gel.
