Recombinant Rhesus Macaque/Cynomolgus IFN-alpha Protein Summary

Product Specifications

>98%, 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.

Interferon was titrated with the use of the cytopathic effect inhibition assay as listed. The protein has similar activity to Human IFN Alpha 2 on human, rhesus and bovine cells.

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.

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

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.
