BDP FL-PEG5-propargyl | CAS 2093197-93-2

BDP FL-PEG5-propargyl is a propargyl-functionalized BODIPY-based fluorescent dye designed for click chemistry labeling workflows. The PEG5 spacer supports conjugation to biomolecules and surfaces while helping maintain dye accessibility for fluorescence imaging. Its reactive propargyl handle enables copper-free or copper-mediated azide-alkyne cycloaddition strategies used in fluorescence microscopy, flow cytometry sample preparation, and fluorescent probe construction.

1. Biomolecule Click Labeling

BDP FL-PEG5-propargyl is used by chemical biology and glycobiology groups to fluorescently tag biomolecules through azide-alkyne click conjugation, including labeling of peptides, proteins, and other azide-functional targets prepared for imaging. Researchers typically incorporate the dye into labeling workflows where the PEG spacer improves dye presentation and reduces steric effects, supporting consistent staining of conjugates used for cellular imaging and binding studies.

2. Fluorescent Probe Construction

BDP FL-PEG5-propargyl serves as a building block for assembling fluorescent probes and imaging reagents that require a defined dye payload attached via a click-compatible handle. Probe developers use the propargyl group to attach the BODIPY fluorophore to azide-bearing targeting motifs, affinity ligands, or scaffold molecules, enabling modular fluorescent probe design for microscopy-based localization experiments and fluorescence readouts in biochemical assay development.

3. Surface And Polymer Functionalization

BDP FL-PEG5-propargyl is applied in biomaterials and materials chemistry workflows to create fluorescently labeled surfaces, coatings, and polymer constructs using azide-alkyne click chemistry. Researchers use the dye to visualize material distribution, track surface modification efficiency, and generate fluorescently traceable biomaterial components for microscopy and imaging studies, leveraging the PEG5 linker to promote dye accessibility on heterogeneous substrates.

4. Flow Cytometry Labeling Reagents

BDP FL-PEG5-propargyl is incorporated into fluorescence labeling reagent development for flow cytometry sample preparation when a BODIPY-based fluorophore is desired for multicolor panels. Cytometry users conjugate the dye to azide-functional biomolecules or reagents via click chemistry to generate stable fluorescent conjugates for cell-associated staining and quantitative fluorescence measurements, where the PEG spacer helps maintain labeling consistency across conjugate preparations.
