Product Information

Biological Activity	Measured in antiviral assay using HepG2 cells infected with vesicular stomatitis virus. The ED50 for this effect is typically 1-4 ng/mL.
Description	IL-28A Protein, Mouse, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 21.1 kDa and the accession number is Q4VK74.
Species	Mouse
Expression System	HEK293 Cells
Tag	C-His
Accession Number	Q4VK74
Synonyms	interferon, λ2,interferon, lambda 2,IL-28A,IL28A,Ifnl2,EG330496
Construction	A DNA sequence encoding the mouse IL28A (NP_001019844.2) (Met1-Val193) was expressed with a C-terminal polyhistidine tag. Predicted N terminal: Asp 20
Protein Purity	> 95 % as determined by SDS-PAGE
Molecular Weight	21.1 kDa (predicted); 28.5 and 24.7 kDa (reducing conditions)
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
