Description

17-Fluorescein Estrone is a high-purity, fluorescently labeled derivative of the natural estrogen hormone, estrone. This compound is specifically engineered for use as a critical tracer and detection reagent in advanced biochemical and diagnostic research. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and clinical diagnostics sectors who require precise, sensitive tools for hormone detection, immunoassay development, and molecular imaging studies. The product is supplied under stringent quality controls to ensure batch-to-batch consistency and reliable performance.

Application

• Immunoassay Development: Acts as a fluorescent tracer or hapten in the development of competitive and non-competitive immunoassays for estrone and related estrogens.
• Diagnostic Kit Manufacturing: A key raw material in the production of diagnostic test kits for hormone level monitoring in clinical and research settings.
• Biochemical Research: Used as a fluorescent probe in receptor binding studies, enzyme-linked assays, and other investigative techniques to study estrogen metabolism and signaling pathways.
• Molecular Imaging: Serves as a contrast agent or labeling molecule in fluorescence microscopy and other imaging modalities for cellular and tissue studies.
• Pharmaceutical Analysis: Employed as a reference standard or analytical reagent in the quality control and bioanalytical testing of pharmaceutical products.
• Environmental Monitoring: Can be utilized in the development of assays to detect estrogenic compounds in environmental samples.
