Cynomolgus IL-33 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus IL-33 Protein is expressed from HEK293 with His tag at the N-Terminus.
It contains His109-Ile270 [Accession | A0A2K5W3I1-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 19.2 kDa. Due to glycosylation, the protein migrates to 25-30 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.

SPR Data

Human IL-1RL1, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-33, His Tag with an affinity constant of 23.44 nM as determined in SPR assay (Biacore T200).

背景(Background)

Interleukin-33 (IL-33) is a cytokine belonging to the IL-1 family, playing a role in inflammatory, infectious and autoimmune diseases and expressed in the cellular nucleus in several tissues. High levels of IL-33 are expressed in epithelial barrier tissues and endothelial barriers. ST2 is a receptor for IL-33, expressed selectively on a subset of Th2 cells, mediating some of their functions.
