    Product Description

     

    Interferons (IFN) are a family of cytokines with potent antiviral, antiproliferative and immunomodulatory properties, classified based on their binding specificity to cell surface receptors . Human IFNA2 was originally cloned in the early ‘80s and now more than a dozen closely related IFN alpha subtypes have been identified in both the human and mouse genome, each sharing about 80% amino acid (aa) sequence homology. Structurally, type I IFNs belong to the class of five helicalbundle cytokines, with the IFNA subtypes containing 2 conserved disulfide bonds. The extracellular domain (ECD) of mature human IFNA1, also known as IFNA13, shares 63% aa sequence identity with mouse IFNA1. Two variants of human IFNA1 are known to exist, IFNA1a and IFNA1b, which only differ by a single residue at position 137. The type I IFNs bind to the interferon alpha receptor (IFNAR), which consists of two subunits: IFNAR1 (alpha subunit) and IFNAR2 (beta subunit).

    Purity

    > 96% by SDS-PAGE and HPLC analyses.

    Biological Activity

    Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.0 × 108 IU/mg.

    Endotoxin

    < 1.0 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4, containing 4% mannitol and 1% HSA.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions

     

    1. Avoid repeated freeze-thaw cycle.

    2. For your safety and health, please wear lab coats and disposable gloves for operation.

    3. For research use only.
