Cluster of Differentiation-200 receptor 1 (CD200 R1), also known as OX-2 receptor, is a transmembrane protein in the immunoglobulin superfamily expressed on the surface of myeloid cells and important in the regulation of myeloid cell activity. CD200R1 expression is restricted primarily to mast cells, basophils, macrophages, and dendritic cells while its ligand, CD200, is widely distributed. CD200R1 signaling inhibits the expression of proinflammatory molecules including TNFs, IFNs, and inducible nitric oxide synthase in response to selected stimuli, which implicate that CD200/CD200R1 inhibitory signaling pathway plays a prominent role in limiting inflammation in a wide range of inflammatory diseases.  

 

产品性质

Synonyms	CD200R; CRTR2; MOX2R; OX2R; CD200 R1; CD200 receptor 1; HCRTR2; MOX2 receptor
Accession	AAQ19772
Source	Recombinant Biotinylated Human CD200 R1/CRTR2 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Ala27-Leu266.
Molecular Weight	The protein has a predicted MW of 29.7 kDa. Due to glycosylation, the protein migrates to 52-70 kDa based on Tris-Bis PAGE result.
Physical Appearance	Sterile Filtered White lyophilized (freeze-dried) powder.
Purity	> 95% as determined by SDS-PAGE and HPLC
Endotoxin	< 1.0 EU per 1μg of the protein by the LAL method.
Formulation	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water.

 

运输与保存方法

The products are shipped with ice pack and can be stored at -20℃ for 1 year.

2-7 days, 2 to 8 °C under sterile conditions after reconstitution.
3 -6 months, -20 to -80°C under sterile conditions after reconstitution.

Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
