CD200 R1/CRTR2[Biotin], His & Avi, Human

CD200 R1/CRTR2[Biotin], His & Avi, Human

CD200Fc, a chimeric molecule including the extracellular domain of CD200 and a murine IgG2a Fc region, regulates immune responses following engagement of a cell surface receptor, CD200R, expressed on cells of the myeloid and T cell lineage. A recent report focused attention on a family of CD200Rs, but concluded that only one member used CD200 as its ligand.

Conjugate Biotin
Purity > 95% as determined by Bis­Tris PAGE 
> 95% as determined by HPLC
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized CD200 R1/CRTR2[Biotin], His & Avi, Human at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml) can bind Human CD200, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 29.7 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 52-70 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage & Stability Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles.
