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.
-
ReconstitutionThe 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

Function
Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR. IL31 may function in skin immunity. -
Tissue specificity
Detected at low levels in testis, bone marrow, skeletal muscle, kidney, colon, thymus, small intestine and trachea. -
Cellular localization
Secreted. - Information by UniProt

Whole cell lysate prepared from human eosinophil granulocytes was loaded at 500000 cells.
5-16% gel run under reducing, denaturing conditions.Blocking step performed using 5% BSA for 2 hours at 25°C.
ab106619 used at a 1/200 dilution.Primary antibody used at a 1/100 dilution.
Secondary antibody was an HRP conjugated goat anti-rabbit IgG, used at a 1/200 dilution.The positive control was stimulated with IL-3 (10ng/ml) + IL-5 (10ng/ml) + GM-CSF (10ng/ml) for 30 minutes.
