Human Interferon alpha(rDNA derived) Reference standard

Cat.No.: IFNA-145H
Product Overview: This material is the Reference Standard for interferon alpha consensus (IFN-α Con1) and is intended for use as the primary biological reference standard in bioassays for IFN-α Con1.
Species: Human
Enzyme Unit: 100, 000 International Units per ampoule.
Usage: No attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution Dissolve the total contents of the ampoule in 0.5ml of sterile distilled water and transfer to a sterile container. Rinse the ampoule with 0.4ml of sterile distilled water and add to the first solution. Make up the total volume to 1.0ml with sterile distilled water.

Stability: Reference materials are held at Creative Biomart within assured, temperature- controlled storage facilities and they should be stored on receipt as indicated on the label. Accelerated degradation studies have indicated that this material is suitably stable, when stored at -20°C or below, for the assigned values to remain valid until the material is withdrawn or replaced. These studies have also shown that the material is suitably stable for shipment at ambient temperature without any effect on the assigned values. Once reconstituted, diluted or aliquoted, users should determine the stability of the material according to their own method of preparation, storage and use. Users who have data supporting any deterioration in the characteristics of any reference preparation are encouraged to contact Creative Biomart.
Storage: For economy of use, it is recommended that the final solution or dilutions thereof be sub-divided into several small aliquots and stored at -20°C or below. Avoid repeated thawing/freezing.
