The overall mean potency assigned is 7.9 IU/ampoule. |
| Usage : |
No attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution. Allow the ampoule to equibrate at room temperature for 10 minutes. Reconstitute the total content with 1.0 ml distilled water using gentle agitation. Transfer the content to a plastic tube. Assays should be carried out as soon as possible upon reconstitution. A study in one laboratory has shown that the reconstitued material was stable up to 3 hours when stored on melting ice. It is not recommended to freeze thaw aliquots after reconstitution for subsequent use. |
| Notes : |
This preparation is not for administration to humans. 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 laboratorys 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. |
| Stability : |
Reference materials are held at Creative Biomart within assured, temperature- controlled storage facilities. Reference Materials should be stored on receipt as indicated on the label. The stability of this standard has been assesseed in an accelerated degradation study which involved potency estimation of ampoules stored at elevated temperatures relative to ampoules stored at -150°C. Estimation of predited loss has indicated no loss of activty when stored at -20°C, and at +20°C less that 0.2% activity per year which supports the shipment of this standard at ambient temperature. The accelerated degradation study and real time monitoring will continue for the lifetime of the standard. |
| Storage : |
Unopened ampoules should be stored in the dark at -20° C or below. Please note: because of the inherent stability of lyophilized material, Creative Biomart may ship these materials at ambient temperature. |
