Purity:
Greater than 95.0% as determined by(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized IL-31 in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The IL-31 (1mg/ml) was lyophilized with 20mM Phosphate buffer, 150mM NaCl pH-7.4.
Stability:
Lyophilized IL-31 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL-31 should be stored at 4 °C between 2-7 days and for future use below -18 °C.
Please prevent freeze-thaw cycles.
Activity:
The ED50 was determined by its ability to activate STAT following receptor ligand interaction and found to be
