Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at -80°C. Avoid freeze / thaw cycle. For long term storage it is recommended to add a carrier protein on reconstitution (0.1% HSA or BSA).
This product is an active protein and may elicit a biological response in vivo, handle with caution.
The lyophilised product should be stored at -20oC till use. Once the product has been reconstituted according to the CoA, this can be diluted further in a chosen aqueous buffer containing a carrier protein, such as 0.1% BSA and stored in working aliquots at -20oC for at least 3 months
Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR. IL31 may function in skin immunity.
Detected at low levels in testis, bone marrow, skeletal muscle, kidney, colon, thymus, small intestine and trachea.
