Active Recombinant Human CXCR4 protein

Specification :
| Source : HEK293 | Species : Human | Tag : N/A | Form : The VLPs are highly immunogenic, so the immunization strategy should be optimized (antigen dose, regimen and adjuvant).Supplied as 0.2 μm filtered solution in PBS, pH7.4 with trehalose as protectant. | Bio-activity : Immobilized Human CXCR4 Full Length Protein-VLP at 5 μg/mL (100 μL/well) can bind Human ulocuplumab, Human IgG4 with a linear range of 1-31 ng/mL. | Molecular Mass : Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrance Proteins can be constituted in-situ with VLPs produced from HEK293 cell cultures. These VLPs concentrate conformationally intact membrane proteins directly on the cell surface and produce soluble, high-concentration proteins perfect for immunization and antibody screening. The VLPs provide the display of properly folded membrane proteins in their native cellular membrane in a compact size of 100~300 nm diameter (similar to the size of most viruses) making it optimal targets for dendritic cells in vivo and surface attachment for phage display. | Protein Length : Met 1-Ser 352 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | 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.
