 Purity/Purification    >97% by SDS-PAGE and HPLC analyses.
 Form/Format    Lyophilized from a 0.2mm filtered concentrated solution in PBS.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Section Bar
 Molecular Weight Information    Approximately 15.6 kDa, a single non-glycosylated polypeptide chain containing 135 amino acids
 Biological Activity    Fully biologically active when compared to standard.Measured by its ability to induce STAT3 activation in U-87 MG human glioblastoma/astrocytoma cells. 5 ng/mL of rhIL31 can effectively induce STAT3 activation.
 Endotoxin Level    Less than 1EU/mg of rHuIL-31 as determined by LAL method.
 Reconstitution    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20 degree C. Further dilutions should be made in appropriate buffered solutions.
Section Bar
 Preparation and Storage    This lyophilized preparation is stable at 2-8 degree C, but should be kept at -20 degree C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 degree C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degree C to -70 degree C. Avoid repeated freeze/thaw cycles.
 Other Notes    Small volumes of IL31 protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Related Product Information for IL31 protein

   Human IL-31 is a T-cell derived cytokine that shares several structural and functional characteristics with IL-6, Oncostatin M, LIF, and Cardiotrophin-1. It signals through a receptor complex comprised of GPL (GP130-like, IL- 31RA) and OSMR (Oncostatin M receptor). GPL/OSMR signaling is a strong activator of STAT3 and STAT5, and can also activate STAT1, Jak1, and Jak2 signaling pathways. IL-31 regulated immune responses have been implicated in skin physiology and inflammatory skin diseases.

 NCBI Summary for IL31    IL31, which is made principally by activated Th2-type T cells, interacts with a heterodimeric receptor consisting of IL31RA (MIM 609510) and OSMR (MIM 601743) that is constitutively expressed on epithelial cells and keratinocytes. IL31 may be involved in the promotion of allergic skin disorders and in regulating other allergic diseases, such as asthma (Dillon et al., 2004 [PubMed 15184896]).[supplied by OMIM, Mar 2008]
Section Bar
 UniProt Comments for IL31    IL31: Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR. IL31 may function in skin immunity.
