IL31 Protein, Human, Recombinant (His Tag)
Product Specifications
Synonyms
IL-31 Protein, Human
Gene Name
Interleukin 31
Expression System
HEK293 Cells
Tag
C-His
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method.
Purity
> 95 % as determined by SDS-PAGE.
Activity
Measured by its ability to induce STAT3 activation in U 87 cells.The EDfor this effect is 11-45 ng/mL.
Form
Lyophilized
Buffer
Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
Function
Cytokine Proteins, Growth Factor proteins, Interleukin proteins, Biological Target proteins
Molecular Weight
The recombinant human IL31 consists of 152 amino acids and predicts a molecular mass of 17.3 KDa. It migrates as an approximately 31.8 KDa band in SDS-PAGE under reducing conditions due to glycosylation.
Storage Conditions
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
