Key Product Details
Product Specifications
Source
Chinese Hamster Ovary cell line, CHO-derived rat IFN-beta protein
Endotoxin Level
<1.0 EU per 1 μg of the protein by the LAL method.
Predicted Molecular Mass
19.68 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%. As there
is no international Rat IFN-beta standard, units are determined with respect to the international reference standard for mouse
interferon alpha/beta (mouse IFN-alpha / beta) 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]. Units of activity measured on rat epithelial-like (RATEC) cells with VSV.
