Source: Escherichia Coli.
Physical Appearance and Stability: Lyophilized IL-31 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IL-31 should be stored at 4C between 2-7 days and for future use below -18C.Please prevent freeze-thaw cycles.
Formulation and Purity: The IL-31 (1mg/ml) was lyophilized with 20mM Phosphate buffer, 150mM NaCl pH-7.4. Greater than 95.0% as determined by(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE.
Application:
Solubility: It is recommended to reconstitute the lyophilized IL-31 in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: The ED50 was determined by its ability to activate STAT following receptor ligand interaction and found to be <5ng/ml, corresponding to a specific activity of 200, 000 units.
Shipping Format and Condition: Lyophilized powder at room temperature.
