Recombinant Human Interleukin-31(rHu IL-31)

• Catalog Number: orb1631635
• Category: Proteins
• Description: Recombinant Human Interleukin-31(rHu IL-31)
• Form/Appearance: Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.
• Purity: > 97 % by SDS-PAGE and HPLC analyses.
• MW: Approximately 15.8 kDa, a single non-glycosylated polypeptide chain containing 141 amino acids.
• UniProt ID: Q6EBC2
• Source: Escherichia coli.
• Expression System: Escherichia coli.
• Biological Activity: Fully biologically active when compared to standard. The specific activity is determined by inducing STAT3 activation using human U-87 MG cells. 5 ng/mL of rHuIL-31 can effectively induce STAT3 activation.
• Storage: This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.
• Note: For research use only
• Expiration Date: 6 months from date of receipt.
