Cynomolgus IL-31 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus IL-31 Protein is expressed from HEK293 with His tag at the N-Terminus.
It contains Leu27-Thr163 [Accession | G7PJ78-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 16.5 kDa. Due to glycosylation, the protein migrates to 23-30 kDa based on Bis-Tris PAGE result.

纯度(Purity)

>95% as determined by Bis-Tris PAGE

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

SPR Data

Human IL-31 RA, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-31, His Tag with an affinity constant of 1.32 nM as determined in SPR assay (Biacore T200).

背景(Background)

Many autoimmune skin diseases, such as bullous pemphigoid (BP), psoriasis and certain types of chronic urticaria, are associated with intensive pruritus. While histamine and neuropeptides have previously been ascribed to play a role in itch that accompanies these diseases, recent evidence suggests that the pruritogenic cytokine interleukin (IL)-31 is a major driver of pruritic responses. IL-31 was originally shown to be produced by activated helper T cells, particularly Th2 cells, mast cells, macrophages and dendritic cells.

分子别名(Synonyms)

Interleukin-31; IL-31;IL31
