BDP FL-PEG5-azide | CAS 2093197-91-0

BDP FL-PEG5-azide is a BODIPY-based fluorescent azide designed for click chemistry labeling workflows, enabling efficient incorporation of a bright fluorophore into biomolecules, polymers, and surfaces through azide-alkyne cycloaddition. The PEG spacer supports conjugation flexibility and helps maintain fluorophore accessibility for imaging and quantitative fluorescence readouts. In practice, researchers use this reagent to build fluorescent conjugates where a stable BODIPY signal is needed for microscopy, flow cytometry, and fluorescence-based assay development.

1. Biomolecule Labeling

BDP FL-PEG5-azide is used by chemical biology and bioconjugation groups to fluorescently tag proteins, peptides, and other biomolecules that have been functionalized with complementary alkyne handles. The azide functionality allows downstream click labeling to install the BODIPY fluorophore with minimal perturbation of the biomolecule's core structure, while the PEG5 linker improves labeling uniformity and reduces steric constraints around the dye. Fluorescently labeled biomolecules prepared with this reagent are commonly applied in binding studies, localization experiments, and quantitative fluorescence assays using standard plate readers and fluorescence microscopes.

2. Fluorescent Probe Construction

BDP FL-PEG5-azide supports fluorescent probe development where a modular labeling step is preferred, such as constructing multi-component imaging reagents or tracer conjugates. Teams in fluorescence chemistry and molecular imaging often use the azide as a "click-ready" fluorophore unit to assemble probe architectures onto targeting ligands, scaffolds, or nanoparticles bearing alkyne groups. The resulting BODIPY-labeled constructs are then evaluated for signal reporting in cellular imaging workflows, including experiments that require robust dye attachment for multi-step assay pipelines.

3. Surface And Polymer Functionalization

BDP FL-PEG5-azide is also leveraged in biomaterials and materials science to introduce fluorescent tags onto PEGylated polymers, hydrogel networks, and solid supports that present alkyne functionalities. By installing the BODIPY fluorophore via click chemistry, researchers can create fluorescently traceable materials for surface characterization, coating uniformity studies, and imaging-guided materials experiments. This approach is frequently used in translational materials workflows where fluorescent readouts are needed to track immobilized biomolecules, study surface interactions, or validate functionalization strategies during material fabrication and testing.

4. Flow Cytometry Labeling

BDP FL-PEG5-azide is used to generate fluorescent conjugates for flow cytometry when a click-compatible labeling strategy is required for consistent dye installation. Laboratories in cell biology and assay development typically prepare alkyne-functional biomolecule reagents and then use the azide fluorophore to label them, enabling controlled fluorescent staining for cell-associated readouts. The PEG spacer helps maintain dye accessibility for efficient excitation and detection, supporting workflows that involve quantitative gating of labeled populations and comparative fluorescence measurements across experimental conditions.
