Interferon-alpha (IFN-alpha, IFNA), 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. There are at least 18 different IFNA subtypes, and the major subtypes identified are IFNA1, IFNA2, IFNA8, IFNA10, IFNA14 and IFNA21.

IFN- alpha I Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN- alpha I Antibody.
Recombinant Human IFN- alpha I reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of EMCV activity elicited by Recombinant Human IFN- alpha I (20 pg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IFN- alpha I Monoclonal Antibody (Catalog # MAB10080). The ND50 is typically 0.6-6 ng/mL.Applications for Human IFN-alpha I Antibody (995826)
Application
Recommended Usage
Neutralization
Measured by its ability to neutralize IFN‑ alpha I inhibition of EMCV-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line. Meager, A. (1987) in Lymphokines and Interferons, a Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 129. The Neutralization Dose (ND50) is typically 0.6-6 ng/mL in the presence of 20 pg/mL Recombinant Human IFN‑ alpha I.
