Human CD200R (C-His) on SDS-PAGE under reducing condition (P+) and non-reducing condition (P-). The gel was stained for 1 hour with BlinkBlue (catalog 700102). The purity of this protein appears to be greater than 95% based on reducing conditions.
Human CD200R (C-His) is coated at 2 ug/mL (200 ng/well). Human CD200 (C-Fc) can bind human CD200R in a dose-dependent manner with the ED50 of 2-20 ng/mL
Biotinylated Human CD200 (C-Fc-Avi) is coated at 2 ug/mL (200 ng/well). Human CD200R (C-His) can bind human CD200 in a dose-dependent manner with the ED50 of 10-50 ng/mL

Not tested
Protein Concentration
25µg size is bottled at 0.2mg/mL concentration. 100 µg size is supplied at a lot-specific concentration.
Storage and Handling
Briefly centrifuge the vial upon receipt. An unopened vial can be stored at 4°C for up to 2 weeks, or at -20°C or below for up to six months. The protein may be further diluted to 0.1 mg/mL using 0.22 µm-filtered PBS buffer (pH 7.4). For long-term storage, the diluted stock solution should be aliquoted and stored at ≤ –70°C to minimize freeze-thaw cycles. If additional dilution is required, carrier proteins such as FBS or BSA should be added to maintain protein stability.
Background Information
The cluster of differentiation (CD) system is essential for immunophenotyping, with over 320 unique CD molecules and subclusters identified to date. These CD molecules play various roles in immune cells, either acting as receptors or ligands to initiate signaling cascades that alter cell behavior, or serving non-signaling functions like cell adhesion. CD200 receptor 1 (CD200R1), an isoform of CD200 receptors, is a cell surface glycoprotein expressed on myeloid lineage cells. It serves as a receptor for the OX-2 membrane glycoprotein, and the interaction between CD200R1 and OX-2 functions as a downregulatory signal for myeloid cells, playing a role in immune regulation.
