Product Information

Biological Activity	Measured by its ability to induce STAT3 activation in U‑87 cells. The ED50 for this effect is 11-45 ng/mL.
Description	IL-31 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 17.3 kDa and the accession number is Q6EBC2.
Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	Q6EBC2
Synonyms	interleukin 31,IL-31
Construction	A DNA sequence encoding the human IL31 (NP_001014358.1) (Met1-Thr164) was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Ser 24
Protein Purity	> 95 % as determined by SDS-PAGE
Molecular Weight	17.3 kDa (predicted); 31.8 kDa (reducing condition, due to glycosylation)
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 shipping with blue ice.
