{"product_id":"biolegend-285417","title":"Biolegend, 285417, Spark YG™ 581 anti-mouse CD64 (FcγRI) (Flexi-Fluor™) Antibody, 50μg","description":"\u003cp\u003eCD64 is a 72 kD single chain type I glycoprotein also known as FcγRI and FcRI. CD64 is a member of the immunoglobulin superfamily and is expressed on monocytes\/macrophages, dendritic cells, and mast cells. The expression can be upregulated by IFN-γ stimulation. CD64 binds IgG immune complex. It plays a role in antigen capture, phagocytosis of IgG\/antigen complexes, and antibody-dependent cellular cytotoxicity (ADCC).\u003cbr\u003e\n50μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: BALB\/c mouse FcγRI-human IgG Fc fusion protein.\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with Spark YG™ 581 under optimal conditions.\u003cbr\u003e\nConcentration: 0.2 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.\u003cbr\u003e\nApplication: FC\u003cbr\u003e\nRecommended Usage: Flexi-Fluors™ are provided at a standard 0.2 mg\/mL concentration. We recommend titrating this reagent to determine the optimal concentration for each application. For many flow cytometry applications, conjugated antibodies perform well at concentrations ranging from 0.03 to 1.0 µg per million cells in 100 µL. We recommend testing a range of concentrations starting from 10 µg\/mL. For example, make five 1:1 serial dilutions of the 0.2 mg\/mL antibody. Add 5 µL of each dilution (including the undiluted antibody) to 100 µL of cells (at 107 cells\/mL) to test six concentrations -- 1.0, 0.5, 0.25, 0.125, 0.06, and 0.03 µg per million cells in 100 µL volume. Compare staining patterns or create a titration curve using the MFI or staining index to determine the optimal concentration. * Spark YG™ 581 has a maximum excitation of 562 nm and a maximum emission of 581 nm.\u003cbr\u003e\nExcitation Laser: Green Laser (532 nm)\/Yellow-Green Laser (561 nm)\u003cbr\u003e\nApplication Notes: The X54-5\/7.1 antibody reacts with mouse strains carrying CD64a and b alleles but not CD64d. X54-5\/7.1 recognizes a conformational determinant formed between domains 2 and 3. Additional reported application (for relevant formats) include: immunoprecipitation1, and spatial biology (IBEX)5,6. Clone X54-5\/7.1 is not found to be useful for Western blots1.\u003cbr\u003e\nAdditional Product Notes: For more information about Flexi-Fluors™, visit our Flexi-Fluor™ page and review FAQs associated with this product line.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Tan PS, et al. 2003.

The technology, manufacturing processes, and specifications used to create Flexi-Fluors are the same as our regular catalog products. However, the optimal concentration and performance of each Flexi-Fluor must be determined by the customer.\u003cbr\u003e\nQ: How quickly will I receive my order?\u003cbr\u003e\nA: We aim to ship Flexi-Fluors within 2-3 weeks of receipt of your order. However, depending on your location, shipping times may vary.\u003cbr\u003e\nQ: How are Flexi-Fluors different from regular catalog products?\u003cbr\u003e\nA: Flexi-Fluors are made on demand, specifically for you. Flexi-Fluors are manufactured using the same high-quality standards, and specifications as other catalog products. For faster delivery, Flexi-Fluors are not tested by flow cytometry to determine optimal concentrations or evaluate performance. This testing needs to be performed by the customer.\u003cbr\u003e\nQ: How do I determine the optimal concentration for using my Flexi-Fluor? How should I titrate my antibody?\u003cbr\u003e\nA: Flexi-Fluors are provided at a standard 0.2 mg\/mL concentration. We recommend that you titrate your antibody to determine the optimal concentration to use for your application. For many flow cytometry applications, conjugated antibodies perform well at concentrations ranging from 0.03 to 1.0 µg per million cells in 100 µL volume. We recommend that you test a range of concentrations starting from 10 µg\/mL. \u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eFor example, make five 1:1 serial dilutions of your 0.2 mg\/mL antibody.  Add 5 µL of each dilution (including the undiluted antibody) to 100 µL of cells (at 107 cells\/ml) to test six concentrations - 1.0, 0.5, 0.25, 0.125, 0.06, and 0.03 µg per million cells in 100 µL volume.
