Cat. No.	Z100525
Name	Recombinant Human IL31
Description	IL-31 is a recently discovered helical cytokine, belonging to the gp130/IL-6 cytokine family. The receptors for IL-6 family are type I receptors, and they share a number of common structural motifs, such as the cytokine-binding domain with two pairs of conserved cysteine residues and a WSXWS sequence motif in the extracellular domain. IL-31 is expressed preferentially by activated Th2 CD4+ T cells, signaling through a heterodimeric receptor complex composed of IL-31RA and OSMR. Recent studies in both humans and mice have suggested a link between IL-31/IL-31R expression and skin inflammation although the functional significance of endogenous IL-31/IL-31R interactions in influencing innate and adaptive immune responses remains unknown.

Family	Other Interleukins
Aliases	IL-31
Gene Symbol	IL31
Gene ID	386653
Accession Number	Q6EBC2
Source	E. coli
Species	Human (H. sapiens)
Appearance	Lyophilized Powder
Molecular Weight	18 kDa
Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method.
Purity	>95% as determined by SDS-PAGE
Formulation	Recombinant Interleukin-31 was lyophilized from a 0.2 μm filtered PBS solution pH 7.5.
Function	The ED(50) was determined by the ability to induce STAT3 activation in U87 MG cells, and was determined to be not less than 7.0 ng/mL.
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage	For research use only. Not for diagnostic or therapeutic use.
Material Citation	If use of this material results in a scientific publication, please cite the material in the following manner: Applied Biological Materials Inc, Cat. No. Z100525

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.
