Recombinant Human IFN-alpha H2 (alpha 14) Protein Summary

Purity
>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain.
Endotoxin Level
<1.0 EU per 1 μg of the protein by the LAL method.
Activity

Interferon was titrated with the use of the cytopathic effect inhibition assay as listed:

Bovine (MDBK/VSV) – performed as described [Rubinstein, et al. (1981) J. Virol. 37(2):755]. The EC50 for interferon in this assay is ~5 U/ml. Lot Activity was derived from multiple determinations in the above assay.

Human (A549/EMCV) – performed as described [Budd, et al. (1985) Canc. Chem. Pharm. 12:39]. The EC50 for interferon in this assay is ~1 U/ml.

Background: IFN-alpha H2

Interferon-alpha (IFN-alpha), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface receptor composed of two subunits, a 100 kDa ligand-binding subunit (IFN-alpha R2) and a 125 kDa ligand binding and signal transduction subunit (IFN-alpha R1) that is involved both in ligand binding and signal transduction. IFN-alpha has both anti-viral and immunomodulatory activities on target cells.
