Sample Preparation

1. Withdraw contents of ampule using a 10 ml syringe with a 1 inch 21 guage needle. Add to a 50 ml vial, preferably with a narrow neck.

2. Dissolve 50 mg of antigen in 5 ml sterile PBS, pH 7.0-7.3. Maintain or create sterility if at all feasible. Draw the solution into the syringe.

3. Insert needle into adjuvant vial and forcibly drive solution into the vial. Withdraw about half the mixture into syringe and force it into the adjuvant vial again.

4.Repeat the mixing procedure in step 4 until a smooth, stable, milky, water-in-oil emulsion forms. Mixture may seem to thicken as the emulsion forms. Check if the emulsion is complete by expelling a drop from the syringe onto the water surface in a beaker. If the drop remains on the surface and does not disperse when the beaker is agitated slightly, the emulsion is adequate. A properly prepared emulsion is stable for days.
