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.
