Neutralization

One neutralization unit is the amount of antiserum required to neutralize one unit of human interferon alpha (Hu-IFN-alpha ) 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-alpha 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]. This material is prepared specifically for effective neutralization of Hu-IFN-alpha.

Please Note: Optimal dilutions should be determined by each laboratory for each application.

Formulation, Preparation and Storage

Purification	N/A
Formulation	Supplied frozen as neat serum.
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. Thaw product vial by incubation in cold tap water until just thawed – 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).

Background: IFN-alpha

Interferon-alpha (IFN-alpha), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface receptor composed of two subunits, a 100 kDa ligand-binding subunit (IFN-alpha R2) and a 125 kDa ligand binding and signal transduction subunit (IFN-alpha R1) that is involved both in ligand binding and signal transduction. IFN-alpha has both anti-viral and immunomodulatory activities on target cells.
