Cellulose acetate electrophoresis :
1. Prepare Haemolysate from whole blood (in K2EDTA) .
2. Prepare the electrophoresis tank by filling the tank with 900ml of TEB buffer wicks are cut from Grade Number 3 chromatography paper and were placed along the 22 cm long bridges in the tank.
3. The cellulose acetate membranes are cut in 40xl00 mm each and soaked in TEB buffer for 5 minutes. 5 strips are plotted then placed on the electrophoresis tanks.
4. Supply the voltage current at 250 V for 5 minutes to the membranes to equilibrate the membranes with the buffer.
5. The current is turned off and apply 8-10 μl haemolysate (10 g/μl on
