Specificity
Binds to human interferon beta with high affinity. For best results in experiments involving neutralization of
the anti-viral effects of human interferon beta we recommend using Sheep Polyclonal Antibody to human interferon beta
(Product 31400-1).

Applications for Human IFN-beta Antibody
Application
Recommended Usage
Neutralization
One neutralization unit is the amount of antiserum required to neutralize one unit of
human interferon beta (Hu-IFN-
beta) to a 50% endpoint. 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 Hu-IFN-
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].
Due to the variation in ND50 (Neutralizing Dose) values based on the cell type and assay system, we recommend each user determine the neutralizing concentration of this antibody lot in their assay system. Using an A549/EMCV (cell/virus) system, we have not verified with reasonable consistency the neutralizing concentration of this antibody (the concentration required to inhibit the antiviral effect of human interferon beta by one half).

Please Note: Optimal dilutions of this antibody should be experimentally determined.
Formulation, Preparation, and Storage
Purification
Protein A or G purified from hybridoma culture supernatant
Formulation
Phosphate-buffered saline (PBS) containing 0.1% bovine serum albumin (BSA)
Shipping
The product is shipped with dry ice or equivalent. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage
After receipt, the product may be stored at -20°C for short-term use (
≤ 6 months). For
long-term storage, we recommend storing the product at -70°C or below for retention of full activity. When thawing, the
contents of the tube should be apportioned in separate tubes so that freezing and thawing is kept to a minimum. Refreezing
should be done on dry ice or in a dry ice/alcohol bath. Further dilution of the product should be in buffers
containing protein such as 0.1% bovine serum albumin (BSA).
