2. CAUTION

This preparation is not for administration to humans or animals in

the human food chain.

The preparation contains material of human origin, and either the final

product or the source materials, from which it is derived, have been

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.

3. UNITAGE

The assigned potency is 100,000 arbitrary units per ampoule.

4. CONTENTS

Country of origin of biological material: United Kingdom.

Each ampoule contains the residue after freeze-drying of 1.0 ml of a

solution that contained:

Approximately 100 ng IL-1 beta (100,000 Units)

0.1 M potassium phosphate buffer

1.0 mg Trehalose

2.0 mg human serum albumin

The IL-1 beta protein was expresed in E.coli.

5. STORAGE

Unopened ampoules should be stored at -20°C. For economy of use, it is

recommended that the solution be sub-divided into several small aliquots

and stored at –40°C or below.

Please note: because of the inherent stability of lyophilized

material, NIBSC may ship these materials at ambient temperature.

6. DIRECTIONS FOR OPENING

DIN ampoules have an 'easy-open' coloured stress point, where the

narrow ampoule stem joins the wider ampoule body. Various types of

ampoule breaker are available commercially. To open the ampoule,

tap the ampoule gently to collect material at the bottom (labelled) end

and follow manufactures instructions provided with the ampoule

breaker.

7. USE OF MATERIAL

No attempt should be made to weigh out any portion of the freeze-dried

material prior to reconstitution

For all practical purposes, each ampoule contains the same quantity of

the substances listed above. Dissolve the total contents of the ampoule in

0.5 ml of sterile distilled water. Rinse out the ampoule with a further 0.4ml

sterile distilled water and make up the amount to 1ml. The concentration

is then at 100,000 units per ml. For further dilution use carrier protein.
