R&D Systems, part of Bio-Techne | Catalog # 11101-1
Key Product Details
Product Specifications
Source
E. coli-derived human IFN-alpha A protein
Endotoxin Level
<1.0 EU per 1 μg of the protein by the LAL method.
Predicted Molecular Mass
19.2 kDa
Activity
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 a cytopathic effect of 50%. The units
are determined with respect to the international reference standard for human interferon alpha A (Hu-IFN-
alphaA) provided by
the National Institutes of Health [see Pestka, S. (1986) "Interferon Standards and General Abbreviations," in
Methods in
Enzymology
(S. Pestka, ed.), Academic Press, New York 119, 14-23]. Unit of activity measured on bovine MDBK cells
with vesicular stomatitis virus (VSV).
