Species of Origin
His Tag (N-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 19.93 kDa.
The protein migrates as 17-25 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to protect L929 cells infected with encephalomyocarditis (EMC) virus. The ED₅₀ for this effect is <10 pg/mL. The specific activity of recombinant mouse IFN alpha 1a is > 4 x 10⁷ IU/mg.
<0.1 EU per 1 μg of the protein by the LAL method.
Interferon Alpha 1a (IFN alpha 1a) is a leukocyte interferon,
which is a variant of Interferon-alpha. IFN-alpha 1a is a
18.4 kDa protein containing 166 amino acid residues. It could bind the interferon receptors that activates the signal transduction of immune responses through the Jak/STAT pathway in leukocytes and lymphoblastoid cells.
Interferon alpha-1, IFN-alpha-1
