Storage Conditions	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Molecular Weight	The protein has a calculated MW of 16.78 kDa. The protein migrates as 18 kDa under reducing condition (SDS-PAGE analysis).
Manufacturer - Format	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us.
Calculated Molecular weight	The protein has a calculated MW of 16.78 kDa.The protein migrates as 18 kDa under reducing condition (SDS-PAGE analysis).
Gene Name	IL31
Purification	>98% as determined by SDS-PAGE.
Reconstitution	Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
Description	Interleukin 31 (IL-31) is an 18 kDa cytokine with 142 amino acid residues. IL-31 is mainly secreted from activated CD4+ T cells and binds to a receptor called IL-31RA. Upon binding to 31RA, IL-31 activates several signal pathways like MAPK, PI3K/AKT, and Jak/STAT pathways. It is critical in regulating many biological functions, such as cell proliferation, hematopoiesis, induction of cytokines, inflammation, and immune response.
Bioactivity/Biological Activity	Measured by its ability to induce A549 cells proliferation. The ED₅₀ for this effect is < 40 ng/mL
Endotoxin level	<0.1 EU per 1 μg of the protein by the LAL method.
