Description

Interferons are divided into type I, II, and III. Type I IFNs (IFN-α and IFN-β) are most abundant in number, distribution, and expression. Also, they are highly conserved among mammals in both structure and function. IFN-α2 has been used in the treatment of cancer such as bladder cancer, hepatocellular carcinoma, and leukemia. IFN-α2 augments the suppressed immune functions in patients with head and neck squamous cell carcinoma (HNSCC). IFN-α2 initiated T and NK cell mediated cytotoxicity of tumor cells through IFNγ dependent and independent mechanisms. IFN-α2 enhances suppressed T cell cytotoxicity by stimulation of the perforin-granzyme B system (IFNγ dependent). Also, IFN-α2 induces the expression of perforin-granzyme B in NK cells (NK mediated cytotoxicity, IFNγ independent). In a preliminary study, IFN-α2 appears to be an effective immunostimulator and impacts the clinical outcome in tongue squamous cell carcinoma patients. IFN-α had been used in the treatment of chronic hepatitis C (CHC); nevertheless, IFN-α is relatively unstable and requires frequent parenteral administration. Pegylation of IFN-α, polyethylene glycol (PEG)-IFN-α, reduces in vitro activity but increase the stability and plasma half-life of IFN-α; therefore, PEG-IFN-α has replaced IFN-α in CHC treatment.

Application

ELISA Capture - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA Capture applications, a concentration range of  2.0 - 8.0 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of IFN-α2 recombinant protein ranging from 12.5 to 800 pg/mL is recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The pure M4509E12 antibody is useful as the capture antibody in a sandwich ELISA assay, when used in conjunction with the biotinylated BL25372 antibody (Cat. No. 537204) as the capture antibody and Recombinant Human IFN-a2 (ELISA Std.) (Cat. No. 592709)

RRID
AB_2783346 (BioLegend Cat. No. 537102)

Antigen Details

Distribution

IFN-α is ubiquitously expressed.

Function
IFN-α stimulates cytotoxic T lymphocytes and natural killer cell function. IFN-α has immunomodulatory and antiviral properties. IFNα2a induces CXCL10 in human microvascular endothelial cells and pulmonary artery smooth muscle cells. It is induced by viral infection.
Interaction
A variety of cells express the IFNα receptor (IFNAR).
Ligand/Receptor
IFNAR complex has two components, IFNAR1 and IFNAR2.
