Molecular Weight (g/mol)	19.2 kDa
Common Name	Interferon alpha-2
Gene Symbol	IFNA2
Activity	Specific activity = 4.0x10e8 units/mg; Assay used to measure bioactivity: interferon was titrated with the use of the cytopathic effect inhibition assay as described [Rubinstein, S., Familletti, P.C., and Pestka, S. (1981 Convenient Assay for Interferons, J. Virol. 37, 755-758; Familletti, P.C., Rubinstein, S., and Pestka, S. (1981) A Convenient and Rapid Cytopathic Effect Inhibition Assay for Interferon, in Methods in Enzymology, Vol. 78 (S. Pestka, ed.), Academic Press, New York, 387-394]. In this antiviral assay for interferon about 1 unit/mL of interferon is the quantity necessary to produce 50% cytopathic effect. The units are determined with respect to the international reference standard for human interferon-alphaA (Hu-IFN-α? provided by the National Institutes of Health [see Pestka, S. (1986) Interferon Standards and General Abbreviations, in Methods in Enzymology Vol. 119 (S. Pestka, ed.), Academic Press, New York, 14-23].
