{"product_id":"biolegend-106341","title":"Biolegend, 106341, PerCP\/Fire™ 806 anti-mouse CD152 Antibody, 25μg","description":"\u003cp\u003eCD152, also known as CTLA-4 or Ly-56, is a 33 kD member of the immunoglobulin superfamily. It is expressed on activated T and B lymphocytes. CD152 is similar to CD28 in amino acid sequence, structure, and genomic organization and these two receptors share common B7 family counter-receptors (B7-1, B7-2). Whereas CD28 delivers a costimulatory signal in T cell activation, CTLA-4 negatively regulates cell-mediated immune responses. CD152 is thought to play a role in the induction and maintenance of immunological tolerance as well as the development of protective immunity and thymocyte regulation.\u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Armenian Hamster\u003cbr\u003e\nImmunogen: Mouse CTLA-4-mouse IgG2a 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 PerCP\/Fire™ 806 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 - Quality tested\u003cbr\u003e\nRecommended 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 ≤ 1.0 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.* PerCP\/Fire™ 806 has a maximum excitation of 478 nm and a maximum emission of 806 nm.\u003cbr\u003e\nExcitation Laser: Blue Laser (488 nm)\u003cbr\u003e\nApplication Notes: The UC10-4B9 antibody can enhance T cell co-stimulation by blocking CTLA-4 interactions with the B7 co-receptors, favoring CD28 interactions. Additional reported applications (for the relevant formats) include: immunoprecipitation1, in vitro stimulation, in vitro and in vivo blocking1-4 of ligand binding, and as ELISA capture antibody5. To reduce non-specific binding to cells bearing Fc-receptors, pre-incubation of cells with anti-mouse CD16\/CD32, clone 93 (Cat. No. 101301\/101302), is recommended prior to immunofluorescent staining. For most successful immunofluorescent staining results, it may be important to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate (Cat. No. 106306) or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated anti-Armenian hamster IgG (Cat. No. 405501) second step, followed by SAv-PE (Cat. No. 405204)). The Ultra LEAF™ purified antibody (Endotoxin \u0026lt; 0.01 EU\/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 106327).\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Walunas TL, et al. 1994. Immunity 1:405. (Block, IP) Cilio CM, et al. 1998. J. Exp. Med. 188:1239.
