产品描述:
Interleukin-33 (IL-33) is a proinflammatory protein that shares structural and functional characteristics with the IL-1 cytokine family. It binds and signals through the IL-1RL1/ST2 receptor activating NF-kappaB and MAP kinases. IL-33 induces production of TH2 cell related cytokines, including IL-4, IL-5 and IL-13, and exerts multiple inflammation related bioactivities.


表达系统 :
Escherichia coli


溶解方法:
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°C. Further dilutions should be made in appropriate buffered solutions.


产品组成:
Lyophilized from a 0.2 μm filtered solution in PBS, EDTA and DTT.


存储条件:
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.


分子量:
Approximately 17.5 kDa protein containing 158 amino acid residues.


内毒素:
Less than 1 EU/μg of IL-33 as determined by LAL method.


产品用途:
This material is offered by Cyagen Biosciences for research, laboratory or further evaluation purposes. FOR RESEARCH USE ONLY. NOT INTENDED FOR ANY ANIMAL OR HUMAN THERAP EUTIC OR DIAGNOSTIC USE.


生物学活性:
The ED50 determined by a cell proliferation assay using murine D10S cells is less than 0.5 ng/mL, corresponding to a specific activity of > 2.0 × 106 IU/mg.


产品形态:
Sterile filtered white lyophilized (freeze-dried) powder.
