• Cat.No.: CD200 R1-3054H
• Product Overview: Biotinylated Recombinant Human CD200 R1 protein(Ala 27-Leu 266), fused with Fc and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&Avi
• ProteinLength: Ala 27-Leu 266
• Form: Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human CD200, Fc Tag at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD200 R1, Fc,Avitag with a linear range of 0.5-7.8 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).The protein has a calculated MW of 55.8 kDa. The protein migrates as 70-115 KDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at-20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after storage at:-20°C to-70°C for 12 months in lyophilized state;-70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
