Description
General Description
BIO-PEG-FITC is a multifunctional fluorescent PEG linker designed for affinity-based labeling and imaging applications. The terminal biotin group binds with exceptionally high affinity to streptavidin and avidin, enabling efficient immobilization, purification, and targeted delivery of biomolecules.
The FITC fluorophore provides strong green fluorescence for visualization by fluorescence microscopy, confocal microscopy, flow cytometry, fluorescence spectroscopy, and other fluorescence-based analytical techniques.
The hydrophilic PEG spacer improves water solubility, molecular flexibility, and biocompatibility while reducing steric hindrance and minimizing nonspecific protein adsorption. This design preserves the accessibility of both the biotin and FITC groups, making BIO-PEG-FITC an excellent reagent for fluorescent labeling, nanoparticle functionalization, biosensor fabrication, targeted drug delivery, and molecular imaging.
