| Molecular Weight | The recombinant human IFN-γR1/Fc is a disulfide-linked homodimeric Protein after removal of the signal peptide. The reduced monomer consists of 475 amino acids and predicts a molecular mass of 53.7 kDa. By SDS-PAGE under reducing conditions, the apparent molecular mass of rhIFN-γR1/Fc is approximately 75-80 kDa due to the glycosylation. |
| predicted N | Glu 18 |
| SDS-PAGE |  |
| Purity | > 97 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the extracellular domain (Met 1-Gly 245) of human IFN-γ receptor 1 pre-protein (NP_000407.1) was fused with C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus. |
| Bio-activity | Measured by its ability to inhibit rhIFNγ mediated protection of WISH cells infected with vesicular stomatitis virus(VSV). The ED50 for this effect is typically 0.4-2 μg/mL. |
| Research Area | Cardiovascular |Angiogenesis |Cytokine & Receptor |Interferon & Receptor |Interferon receptor |
| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| Background | The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD119 (cluster of differentiation 119), also known as IFNGR1 ( interferon gamma receptor 1), is part of the heterodimeric gamma interferon receptor which consists of IFNGR1 (CD119) and IFNGR2. The IFNGR1 gene encodes the ligand-binding chain (alpha) of the interteron receptor while IFNGR gene encodes the non-ligand binding partner. The ability of the interferon-γ was achieved through binding to the interferon receptor CD119. After binding, the products of activated T-lymphocytes interferon-γ exerts antiviral activity, growth inhibitory effect, and several immune- regulatory activities on a variety of cell types. |
