{"product_id":"carboxyl-polystyrene-microspheres-orange-fluorescence","title":"Carboxyl polystyrene microspheres-orange fluorescence","description":"\u003cp\u003eProduct Name Name:Carboxyl polystyrene microspheres-orange fluorescence Product Overview Carboxyl modified orange fluorescent polystyrene microspheres are prepared by adding 540 excited, 610 emitted orange fluorescent dye and modifying carboxyl group in the process of preparing polystyrene microspheres. Customizable size range 80nm-5μm. These microspheres have a uniform particle size distribution, which enables them to show consistent performance in a variety of applications, and fluorescent dyes are embedded inside the microspheres, effectively preventing fluorescence quenching and reducing the influence of environmental factors on fluorescence intensity. Technical Parameter Particle size: ~1um Concentration: 10mg\/ml Product Features Monodispersion: The uniform size distribution of the microspheres helps to ensure the consistency and repeatability of the experimental results. Fluorescence characteristics: Contains high-fluorescence dyes, which are embedded in the inside of the microsphere to effectively prevent fluorescence quenching. Adjustable particle size: By controlling the synthesis conditions, different particle sizes of microspheres can be prepared to meet different application needs. Surface functionalization: The surface of the microsphere can be chemically modified to introduce specific functional groups, such as carboxylic groups, amino groups, etc., to achieve specific biochemical functions. High stability: The microspheres have good chemical and physical stability and are suitable for use in a variety of environments. Optical properties: The fluorescence emission of the fluorescent microsphere is stable and is not affected by changes in the external environmental medium. Application Fields Biomedical research: In the fields of cell biology, molecular biology, and biochemistry, fluorescent polystyrene microspheres can be used for cell labeling, imaging, and as carriers for drug delivery systems. Standard measurement: As an instrument calibration particle, it is used to calibrate analytical instruments and ensure the accuracy of measurement. High-throughput drug screening: serves as a signal carrier to help quickly screen large numbers of compounds and find potential drug candidates. Medical diagnosis: In terms of immunoanalysis and detection, the surface of the microsphere retains the original functional groups, which will not affect immunoanalysis and detection. Tracer study: Fluorescent microspheres can be used as tracers to monitor the process of endocytosis in the fields of phagocytosis study and pore size measurement.
