CD94 belongs to the C-type lectin superfamily and is present as a covalently linked heterodimer with NKG2 on the cell surface. CD94 is expressed by NK cells, a subset of γδ T cells, and NKT cells. The CD94\/NKG2A complex serves as an inhibitory receptor specific for HLA-class I molecules.\u003cbr\u003e\n100tests\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nReported Reactivity: African Green, Baboon, Cynomolgus\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: NK cell line\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions.\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.

For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.\u003cbr\u003e\nExcitation Laser: Blue Laser (488 nm)Green Laser (532 nm)\/Yellow-Green Laser (561 nm)\u003cbr\u003e\nApplication Notes: Additional reported applications (for the relevant formats) include: immunoprecipitation4, inhibition of NK cell-mediated lysis5, immunohistochemical staining of acetone-fixed frozen tissue sections, and spatial biology (IBEX)6,7.\u003cbr\u003e\nAdditional Product Notes: Iterative Bleaching Extended multi-pleXity (IBEX) is a fluorescent imaging technique capable of highly-multiplexed spatial analysis. The method relies on cyclical bleaching of panels of fluorescent antibodies in order to image and analyze many markers over multiple cycles of staining, imaging, and, bleaching. It is a community-developed open-access method developed by the Center for Advanced Tissue Imaging (CAT-I) in the National Institute of Allergy and Infectious Diseases (NIAID, NIH).\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Mizuki M, et al. 2000.

Ultimately a directly conjugated antibody’s utility in fluorescent imaging and IBEX may be specific to the sample and microscope being used in the experiment. Some antibody clone conjugates may perform better than others due to performance differences in non-specific binding, fluorophore brightness, and other biochemical properties unique to that conjugate.\u003cbr\u003e\nQ: Will antibodies my lab is already using for fluorescent or chromogenic IHC work in IBEX?\u003cbr\u003e\nA: Fundamentally, IBEX as a technique that works much in the same way as single antibody panels or single marker IF\/IHC. If you’re already successfully using an antibody clone on a sample of interest, it is likely that clone will have utility in IBEX. It is expected some optimization and testing of different antibody fluorophore conjugates will be required to find a suitable format; however, legacy microscopy techniques like chromogenic IHC on fixed or frozen tissue is an excellent place to start looking for useful antibodies.\u003cbr\u003e\nQ: Are other fluorophores compatible with IBEX?\u003cbr\u003e\nA: Over 18 fluorescent formats have been screened for use in IBEX, however, it is likely that other fluorophores are able to be rapidly bleached in IBEX. If a fluorophore format is already suitable for your imaging platform it can be tested for compatibility in IBEX.\u003cbr\u003e\nQ: The same antibody works in one tissue type but not another. What is happening?\u003cbr\u003e\nA: Differences in tissue properties may impact both the ability of an antibody to bind its target specifically and impact the ability of a specific fluorophore conjugate to overcome the background fluorescent signal in a given tissue. Secondary stains, as well as testing multiple fluorescent conjugates of the same clone, may help to troubleshoot challenging targets or tissues. Using a reference control tissue may also give confidence in the specificity of your staining.\u003cbr\u003e\nQ: How can I be sure the staining I’m seeing in my tissue is real?\u003cbr\u003e\nA: In general, best practices for validating an antibody in traditional chromogenic or fluorescent IHC are applicable to IBEX. Please reference the Nature Methods review on antibody based multiplexed imaging for resources on validating antibodies for IBEX.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46863057289385,"sku":"305506","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/biolegend-305506","provider":"Iright","version":"1.0","type":"link"}
