Biological Activity

The ED50 was determined by a cytotoxicity assay using Human TF-1 cells is < 0.01 ng/ml, corresponding to a specific activity of > 100,000,000 units/mg.

Formulation

Lyophilized from a 0.2um filtered concentrated solution in 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 IFNW1 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 IFNW1 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IFNW1 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

Interferon omega-1, Interferon alpha-II-1, IFNW1.
