Description of target: Inhibitory receptor for the CD200/OX2 cell surface glycoprotein. Limits inflammation by inhibiting the expression of proinflammatory molecules including TNF-alpha, interferons, and inducible nitric oxide synthase (iNOS) in response to selected stimuli. Also binds to HHV-8 K14 viral CD200 homolog with identical affinity and kinetics as the host CD200.;Species reactivity: Human;Application: ;Assay info: Assay Methodology: Quantitative Sandwich Immunoassay;Sensitivity: < 6.6 pg/mL
