Species of Origin
His Tag (C-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 20.61 kDa.
The protein migrates as 17-25 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to protect HepG2 cells infected with encephalomyocarditis(EMC) virus. The ED₅₀ for this effect is <2 ng/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
Interleukin 28A (IL-28A) predicts a molecular mass of 22.3 kDa. IL-28 comes in two isoforms, IL-28A and IL-28B, and plays a role in immune defense against viruses, including the induction of an "antiviral state" by turning on Mx proteins, 2',5'-oligoadenylate synthetase as well as ISGF3G.
