Description

Fluorescein Lisicol is a specialized, high-purity derivative of fluorescein, a cornerstone fluorescent dye. This compound matters for its enhanced solubility and stability profile, making it a critical reagent in advanced diagnostic and research applications. It is primarily needed by manufacturers in the in-vitro diagnostic (IVD) and biotechnology sectors for developing sensitive assays and fluorescent probes.

Application

• Fluorescent Labeling Agent: Used as a key component in the synthesis of fluorescent conjugates for antibodies, proteins, and nucleotides in immunoassays and histochemistry.
• In-Vitro Diagnostic (IVD) Reagents: A vital raw material for manufacturing reagents in clinical chemistry analyzers and point-of-care testing devices.
• Biomedical Research: Employed in cell biology and molecular biology for tracing, staining, and as a fluorescent marker in various experimental protocols.
• Flow Cytometry: Serves as a fluorescent dye for cell sorting and analysis, often after conjugation to specific ligands or antibodies.
• Optical Imaging: Utilized in the development of contrast agents and probes for non-invasive imaging techniques in preclinical research.
• Quality Control in Pharmaceutical Manufacturing: Acts as a tracer or marker in process validation and cleaning verification studies.
