Sulforhodamine B Introduction

Lissamine rhodamine B is a high-quality fluorescent staining dye with excellent water solubility, high fluorescence quantum yield, and bright, stable color. The product boasts high purity, low impurity content, stable chemical properties, a slow fluorescence quenching rate, and excellent optical colorimetric characteristics. It is widely applicable to various scenarios including biological tissue staining, fluorescent labeling, immunohistochemistry, and microscopic imaging. Batch-to-batch uniformity and excellent solubility make it a commonly used core staining raw material in biological research and fluorescence detection.

Specifications

Application area 

Lissamine Rhodamine B is primarily used in biomedical research and in vitro diagnostics, specifically including:

• Cytotoxicity assays: As a core dye in the sulfonylrhodamine B colorimetric method, it is used to determine in vitro cytotoxicity, cell proliferation, and survival rates in drug screening, and is one of the standard detection methods in antitumor drug development.
• Fluorescent probes and molecular markers: Used as a fluorescent marker for aptamer fluorescence anisotropy/polarization analysis, it can be used to detect fungal toxins such as ochratoxin A.
• Blood-brain barrier studies: Used as a microscopic tracer to assess the integrity of the blood-brain barrier through frozen sections from autopsies.
• Dental caries detection: Used as a dye for dental caries detection, assisting in the assessment of caries sites in histological examination materials.
• Tumor molecular imaging probes: Lissamine Rhodamine B can be used as a radioactive tracer for positron emission tomography (PET) imaging studies of mouse tumors.

Main Advantages of Sulforhodamine B

1. Excellent fluorescence performance: Emission wavelength 580 nm (orange-red), excitation wavelength 555 nm, moderate Stokes shift, low background interference, suitable for various fluorescence detection platforms.
2. Anionic dye with good water solubility: Contains two sulfonic acid groups in the molecule, exhibiting excellent water solubility and facilitating use in physiological buffer solutions.
3. High chemical stability: Melting point >300°C, stable during room temperature storage, and maintains fluorescence performance over a wide pH range.
4. Wide range of applications: Mature applications from basic cell staining to high-end molecular imaging probes, making it a versatile fluorescence tool in life science research.
5. Controllable quality and compliance with standards: The product complies with C.I. 45100 standards and can be used as Acid Red 52 in standardized detection procedures.
