FITC-PEG-Mal (Fluorescein-PEG-Maleimide) is a linear heterobifunctional PEG reagent that combines a fluorescein dye (FITC) with a thiol-reactive maleimide group. FITC is widely utilized in biological research for staining cells, tissues, biomarkers, or nanoparticles due to its intense green fluorescence. It absorbs light most effectively at 494 nm and emits light at 521 nm upon excitation, making it suitable for fluorescence microscopy and flow cytometry applications. In PEGylation, FITC-PEG-MAL serves to label or tag biomolecules and nanoparticles, enabling their visualization and tracking within biological systems. This fluorescent PEG derivative plays a crucial role in biomedical research by facilitating the precise labeling and detection of targets of interest.
