Streptavidin-Modified Red Fluorescent Polystyrene Microspheres

Product Overview

Streptavidin-modified red fluorescent polystyrene microspheres are red fluorescent polystyrene microspheres that have been functionalized with streptavidin, creating highly specific probes for various applications. The strong affinity between biotin and streptavidin forms the basis for many biological detection fields. Biotin can covalently bind to various biomolecules, while streptavidin specifically recognizes and binds to biotin, making these microspheres highly useful in biomolecular labeling and detection.

Key Features

• High Biocompatibility: The polystyrene microspheres, after modification with streptavidin, exhibit excellent compatibility with biological systems, making them ideal for interactions with biomolecules.
• High Sensitivity: The high affinity between streptavidin and biotin ensures the microspheres demonstrate high sensitivity in biomolecular detection applications.
• High Specificity: The streptavidin-biotin system offers highly specific binding, significantly improving detection accuracy and precision.

Applications

• Biological Detection and Diagnosis: The microspheres can serve as detection platforms, capturing and detecting specific biomolecules such as proteins, nucleic acids, etc., through the strong streptavidin-biotin interaction.
• Immunoassay: Used in the development of lateral flow assays, enabling high specificity and sensitivity in immunodetection.
• Biosensors: Can be incorporated into biosensors for the detection and analysis of specific biomolecules.
• Fluorescent Microscopy Detection: Due to their fluorescent properties, these microspheres are ideal for use in fluorescent microscopy for cell imaging and tissue observation.
• Quantitative Detection of Biomolecules: Employed in the development of assays for quantitative biomolecular detection, leveraging their high affinity and specificity for target molecules.
