use

Fluorescein is an organic compound with strong fluorescent properties, widely used in various fields, especially in biomedicine, environmental science, and materials science. Below are its main applications:

1. Biomedical Research

• Cell labeling & imaging: Fluorescein can label cells and tissues, allowing observation of cellular behavior and interactions via fluorescence microscopy.
• Gene expression analysis: Fluorescein-labeled probes are used in real-time quantitative PCR to accurately measure gene expression levels.
• Protein studies: Fluorescein-labeled proteins help study protein localization, interactions, and structural changes.
• Immunological detection: Fluorescein-labeled antibodies are used in immunofluorescence assays to detect antigens.

2. Medical Diagnosis & Therapy

• Disease diagnosis: Fluorescein detects biomarkers (e.g., proteins, DNA) for early disease diagnosis.
• In vivo imaging: Fluorescein-labeled probes track tumor growth and metastasis.
• Drug development: Fluorescein studies drug distribution, metabolism, and efficacy in the body.

3. Environmental Science

• Water pollution monitoring: Fluorescein's luminescence helps detect water contamination and ecological changes.

4. Materials Science

• Luminescent materials: Fluorescein is used in LEDs, LCDs, and other optoelectronic devices.

5. Food & Cosmetics

• Food additive: As a natural pigment, fluorescein enhances food color and nutritional appeal.
• Cosmetics: It provides unique luminescent effects in makeup products.

6. Other Applications

• Biosensors: Fluorescein-based sensors detect specific molecules (e.g., SO2, CO).
• Flow cytometry: Fluorescein-labeled cells are analyzed for cellular properties.
