tested and found negative for HBsAg, anti-HIV and HCV RNA. As with

all materials of biological origin, this preparation should be regarded as

potentially hazardous to health. It should be used and discarded

according to your own laboratory's safety procedures. Such safety

procedures should include the wearing of protective gloves and

avoiding the generation of aerosols. Care should be exercised in

opening ampoules or vials, to avoid cuts.

6. DIRECTIONS FOR OPENING

Tap the ampoule gently to collect the material at the bottom (labelled)

end. Ensure ampoule is scored all round at the narrow part of the

neck, with a diamond or tungsten carbide tipped glass knife file or

other suitable implement before attempting to open. Place the

ampoule in the ampoule opener, positioning the score at position 'A';

shown in the diagram below. Surround the ampoule with cloth or

layers of tissue paper. Grip the ampoule and holder in the hand and

squeeze at point 'B'. The ampoule will snap open. Take care to avoid

cuts and projectile glass fragments that enter eyes. Take care that no

material is lost from the ampoule and that no glass falls into the

ampoule.
