Aminated red fluorescent polystyrene microspheres provide optimized surface functionality, superior fluorescence intensity, and enhanced binding efficiency. Designed for biomedical imaging and assay applications, they ensure effective signal detection, extended durability, and high adaptability.
Product Overview
Aminated red fluorescent polystyrene microspheres are synthesized by incorporating red fluorescent dye (excitation wavelength around 535 nm, emission wavelength around 610 nm) and modifying the microsphere surface with amino groups. The fluorescent dye is uniformly encapsulated within the microsphere, preventing fluorescence quenching and minimizing the impact of environmental factors on fluorescence intensity. These microspheres exhibit excellent monodispersity, with uniform particle size, making them suitable for various experiments and applications.
Key Features
- Monodispersity: The microspheres exhibit a uniform particle size distribution, ensuring consistent and reproducible experimental results.
- Fluorescent Properties: The embedded high-fluorescent dye ensures stable fluorescence emission, effectively preventing fluorescence quenching.
- Customizable Particle Size: Particle size can be adjusted based on specific application needs, providing flexibility for various uses.
- Surface Functionalization: The surface of the microspheres can be modified with amino, carboxyl, and other functional groups to support specific biochemical functions.
- High Stability: The microspheres demonstrate excellent chemical and physical stability, making them suitable for use in a variety of environmental conditions.
- Optical Performance: The fluorescent emission remains stable, unaffected by changes in the surrounding medium.
Applications
- Biomedical Research: Widely used for cell labeling, imaging, and as drug delivery system carriers, in cell biology, molecular biology, and biochemistry research.
- High-Throughput Drug Screening: Serve as signal carriers to efficiently screen compounds and identify potential drug candidates.
- Medical Diagnostics: Used in immunoassays and diagnostic tests, with surface functional groups that do not interfere with detection processes.
- Tracer Studies: Ideal for phagocytosis studies, pore size measurements, and other biological research, serving as tracers to monitor cellular processes.
