Biolegend, 112802, Purified anti-mouse CD119 (IFN-γ R α chain) Antibody, 500μg

CDw119 is a 90 kD immunoglobulin superfamily member, also known as IFN-γRα chain. It is a class II cytokine receptor family member that serves as a IFN-γ-binding chain associated with the IFN-γ β chain also known as AF-1. In addition to ligand binding, CDw119 participates in ligand trafficking. CDw119 is expressed on T and B cells, NK cells, fibroblasts, endothelial, and epithelial cells. Binding of IFN-γ induces receptor dimerization, internalization, Jak1 and Jak2 protein kinase activation and, ultimately, STAT1 activation. IFN-γ initiates and regulates a variety of immune responses.
500μg
Verified Reactivity: Mouse
Antibody Type: Monoclonal
Host Species: Armenian Hamster
Immunogen: Soluble recombinant mouse IFN-γR α chain protein
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application: FC - Quality tested IP, WB - Reported in the literature, not verified in house
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes: Additional reported applications (for the relevant formats) include: Western blotting and immunoprecipitation1. The 2E2 antibody does not block the binding of IFN-γ to IFN-γ receptor. For the most successful immunofluorescent staining results, it may be necessary to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody (Cat. No. 112804) or biotinylated anti-Armenian hamster IgG (Cat. No. 405501) second step, followed by SAv-PE (Cat. No. 405204)).
