NS0-derived, recombinant human CD200 R1 (rhCD200 R1, aa1-266: Accession NP_620161). Species sequence homology: mouse, rat (56%).
CD200 R1, also known as OX-2 receptor, is one of four CD200 R-related proteins within the immunoglobulin superfamily. CD200 R1 is a type I transmembrane protein with a PTB-signaling motif in its cytoplasmic domain. Engagement of CD200 R1 by CD200 elicits an inhibitory signal in mast cells, basophils, macrophages, and dendritic cells. Alternate splicing of the human CD200 R1 mRNA generates four isoforms, two of which are truncated in the Ig-C2 domain and are likely secreted. Within the ECD, human CD200 R1 shares 56% aa sequence identity with mouse and rat CD200 R1. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: PE conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
