Biological Activity

The specific activity as determined in a viral resistance assay viral ressistance assay was found to be 100MIU/ mg.

Formulation

Lyophilized from a (1 mg/ml) solution in containing 1X PBS pH-7.4.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 95.0% as determined by
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized IFN alpha 1a in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized Interferon alpha 1a although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IFN-alpha 1a should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms
