Biological Activity

The specific activity as determined in a viral resistance assay (human "Wish" cell line and VSV virus or the monkey VERO cell line with EMCV virus) was found to be 270MIU/mg.

Formulation

Lyophilized from 1mg/10ml solution containing 91 mg Human Albumin, and 620 mg mannitol, and 9 mg Sodium Acetate.

Purity

Greater than 98.0% as determined by
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

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

Source

CHO (Chinese Hamster Ovarian) cells.

Stability

Lyophilized Interferon-beta 1a although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IFN-Beta1a should be stored at 4oC between 2-7 days and for future use below -18oC.
Please prevent freeze-thaw cycles.
