Name : Human PVRIG Protein
Product Source :
Recombinant Human PVRIG Protein is expressed from HEK293 with mFc (IgG1) tag at the C-Terminus. It contains Thr41-Asp171.[Accession | Q6DKI7-1]
Molecular Weight :
The protein has a predicted MW of 39.6 kDa. Due to glycosylation, the protein migrates to 50-65 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
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 and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human PVRIG on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human PVRIG is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human Nectin-2, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Human PVRIG, mFc Tag with the EC50 of 0.17μg/ml determined by ELISA (QC Test). ELISA Data Immobilized Human PVRIG, mFc Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-PVRIG Antibody, hFc Tag with the EC50 of 8.0ng/ml determined by ELISA. SPR Data Human PVRIG, mFc Tag captured on CM5 Chip via Anti-Mouse Antibody can bind Human Nectin-2, His Tag with an affinity constant of 0.349 μM as determined in SPR assay (Biacore T200).
Background :
Human PVRIG (poliovirus receptor related immunoglobulin domain-containing protein), also known as CD112 receptor (CD112R), is an approximately 34 kDa single transmembrane protein in the poliovirus receptor-like protein (PVR) family.PVRIG is a cell surface receptor for NECTIN2. May act as a coinhibitory receptor that suppresses T-cell receptor-mediated signals. Following interaction with NECTIN2, inhibits T-cell proliferation. Competes with CD226 for NECTIN2-binding.
