Biolegend, 127008, FITC anti-mouse CD317 (BST2, PDCA-1) Antibody, 100μg

CD317, known as BST2, tetherin, HM1.2 antigen, bone marrow stromal antigen 2, or PDCA-1, is type II transmembrane glycoprotein with a molecular mass of 29-33 kD. It is predominantly expressed on Type I IFN-producing cells (IPCs) in naïve mice, but is up-regulated on most cell types following stimulation with type I IFNs and IFN-gamma. It is highly expressed on terminally differentiated normal plasmacytoid dendritic cells and some tumor cells, such as multiple myeloma, renal cell carcinoma, and melanoma cells. BST2 is a recently identified, IFN-induced cellular response factor that blocks release of HIV-1 and other retroviruses from infected cells. BST2 has been found to be the natural ligand of ILT7 in human model.
100μg
Verified Reactivity: Mouse
Antibody Type: Monoclonal
Host Species: Rat
Immunogen: Mouse plasmacytoid dendritic cells (DCs)
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with FITC under optimal conditions.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: FC - Quality tested
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.
