Recombinant Protein

Pricing & Availability
Specifications

Purity or Quality Grade	≥95% by SDS-PAGE
Conjugate	Unconjugated
Form	Liquid
Molecular Weight (g/mol)	19.2 kDa
Common Name	Interferon alpha-2b
Gene Symbol	IFNA2
Activity	Specific Activity = 2.38x10e8 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]. The activity was determined with bovine MDBK cells challenged with vesicular stomatitis virus (VSV).
