Product Description	Recombinant Cynomolgus CD200/OX-2 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln56-Gly257.
Product Background	CD200 and its receptors are highly expressed in the lung, on epithelial cells and leukocytes, and emerging evidence links dysregulation of the CD200 pathway with asthma. Moreover, pharmacological modulation of CD200 receptors was shown to improve clinical and inflammatory outcomes of preclinical asthma models.
Product Category	Recombinant Protein

Target	CD200/OX-2
Gene/Protein ID	A0A2K5TQS2
Species	Cynomolgus
Exact Sequence	Gln56-Gly257
Molecular Weight	The protein has a predicted MW of 23.66 kDa. Due to glycosylation, the protein migrates to 45-55 kDa based on Tris-Bis PAGE result.
Activity	Immobilized Cynomolgus CD200, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Human CD200 R1, hFc Tag with the EC50 of 6.2ng/ml determined by ELISA (QC Test). The affinity constant of 35.84 nM as determined in SPR assay (Biacore T200). See testing image for detail.
