Cy5-Modified Polystyrene Microspheres

Product Overview

Cy5-modified polystyrene microspheres are prepared by incorporating the red fluorescent dye Cy5 during the synthesis of polystyrene microspheres. These microspheres exhibit uniform particle size distribution and provide stable red fluorescence, making them ideal for biomedical research, drug screening, medical diagnostics, and more. The fluorescent dye is encapsulated within the microspheres, preventing fluorescence quenching and minimizing the impact of environmental factors on fluorescence intensity.

Key Features

• Monodispersity: The microspheres have a uniform particle size distribution, ensuring consistency and repeatability in experimental results.
• Fluorescence Properties: The microspheres contain high-fluorescence Cy5 dye, which is effectively encapsulated inside the microsphere to avoid fluorescence quenching.
• Adjustable Particle Size: By controlling the synthesis conditions, microspheres with varying particle sizes can be produced to meet different application needs.
• Surface Functionalization: The surface of the microspheres can be chemically modified to introduce specific functional groups (e.g., carboxyl, amine) to achieve targeted biochemical functionalities.
• High Stability: Excellent chemical and physical stability makes these microspheres suitable for use in a variety of experimental environments.
• Optical Performance: The fluorescence emission is stable and unaffected by changes in the external environment or medium.

Applications

• Biomedical Research: Ideal for cell labeling, imaging, and as carriers for drug delivery systems. They are widely used in cell biology, molecular biology, and biochemical research.
• High-Throughput Drug Screening: Used as signal carriers to facilitate the rapid screening of large numbers of compounds to identify potential drug candidates.
• Medical Diagnostics: Suitable for immunoassays, detection, and other diagnostic applications. The microspheres' surface can maintain original functional groups, ensuring no interference in the analysis process.
• Tracer Studies: Can be used as tracers in studies such as phagocytosis, pore size measurement, and other biological studies to monitor cellular uptake processes.
