Scientific Data Images for Human IFN-alpha 2/IFNA2 Antibody

IFN‑ alpha2/IFNA2 Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN‑ alpha2/IFNA2 Antibody.

IFN‑ alpha2/IFNA2 Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN‑ alpha2/IFNA2 Antibody.

Recombinant Human IFN-alpha 2/IFNA2 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 2/IFNA2 (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IFN-alpha 2/IFNA2 Monoclonal Antibody (Catalog # MAB93452). The ND50 is typically 0.6-3.6 ng/mL.

Applications for Human IFN-alpha 2/IFNA2 Antibody

Application
Recommended Usage

Neutralization

Measured by its ability to neutralize IFN‑ alpha2/IFNA2 inhibition of EMCV-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line. The Neutralization Dose (ND50) is typically 0.6-3.6 ng/mL in the presence of 0.25 ng/mL Recombinant Human IFN‑ alpha2/IFNA2.

Background: IFN-alpha 2/IFNA2

Interferon-alpha 2 (IFNA2), also known as leukocyte interferon, is a type I interferon  produced by macrophages,  CD8 resting T cells, tonsillar NK cells, germinal center B cells, as well as epithelial cells, tumor cells and melanocytes. IFN alpha has at least nine different isoforms.

IFNA2 is a ligand for a cell surface receptor with two subunits, IFN-alpha R2 (ligand binding) and IFN-alpha R1 (ligand binding and signal transduction). IFNA2 has both antiviral and immunomodulatory activities on target cells.  Intranasal administration has been shown to reduce viral load in subjects with the common cold. While IFNA2 is a prognostic factor for hepatocellular carcinoma, Interferon alpha 2b, has been used to treat melanoma, renal cell carcinoma, chronic myelogenous leukemia and hepatitis C.
