Applications for Human IFN-alpha Antibody
Application
Recommended Usage
ELISA
Optimal dilutions should be determined by each laboratory for each
application.
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].
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).
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.
