Biological activity: Measured by its binding ability in a functional ELISA. Immobilized recombinant human CD200R1 at 2 μg/ml. The concentration of rhCD200 that produces 50% of the optimal binding response is approximately 0.5‑16 ng/ml.
Results: Measured by its binding ability in a functional ELISA. Immobilized recombinant human CD200R1 at 2 μg/ml. The concentration of rhCD200 that produces 50% of the optimal binding response is approximately 0.5‑16 ng/ml.
Binding Capacity: N/A
Unit Definition: N/A
Molecular Weight: This protein is fused with 6×His tag at the C-terminus, has a calculated MW of 23.4 kDa. The predicted N-terminus is Gln 31. DTT-reduced Protein migrates as 35-45 kDa due to glycosylation.
Concentration: N/A
Appearance: Lyophilized
Physical form description: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.
Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
Background Information: CD200 also known as OX-2 membrane glycoprotein (OX-2), is a type-1 membrane glycoprotein, which contains two immunoglobulin domains (1 Ig-like C2-type (immunoglobulin-like) domain and Ig-like V-type (immunoglobulin-like) domain), and thus belongs to the immunoglobulin superfamily. CD200 / OX-2 is widely expressed in multiple cell types. CD200 interacts with a structurally related receptor (CD200R) expressed mainly on myeloid cells and is involved in regulation of macrophage and mast cell function. OX-2 / CD200 and CD200R associate via their respective N-terminal Ig-like domains. CD200 also plays an important role in prevention of graft rejection, autoimmune diseases and spontaneous abortion.
Amino acid sequence: N/A
Handling: Centrifuge the vial prior to opening.
Usage: For Research Use Only! Not to be used in humans
