Fluorescein-PEG5-Acid CAS:2183440-40-4 is a xanthene dye with excitation/emmission maximum 494/517 nm and a free terminal carboxyl acid.
Fluorescein-PEG5-Acid is a versatile molecular probe, composed of a fluorescein moiety, a hydrophilic polyethylene glycol (PEG) linker, and a carboxylic acid functional group. The fluorescein imparts strong fluorescence, while the PEG linker enhances solubility and reduces non-specific interactions. The terminal carboxylic acid group facilitates conjugation to various biomolecules, rendering it an invaluable tool for researchers.
In pharmaceutical research and development, Fluorescein-PEG5-Acid plays a crucial role as a fluorescent labeling agent for biomolecule detection and quantification. Its applications include drug delivery studies, cell tracking, receptor binding analysis, and enzyme-substrate interactions. The probe’s unique properties promote improved sensitivity, specificity, and real-time monitoring, thus enabling researchers to advance drug discovery and development with remarkable precision and efficiency.
