BDP FL DBCO | CAS 2093197-94-3

BDP FL DBCO is a fluorescent DBCO (dibenzocyclooctyne) click reagent designed for strain-promoted azide-alkyne cycloaddition (SPAAC)-based bioconjugation. The BDP FL fluorophore enables fluorescence readouts after rapid, catalyst-free labeling of azide-functional biomolecules, making it useful for constructing fluorescent conjugates for imaging and assay development.

1. Biomolecule Labeling

BDP FL DBCO is used by chemical biology and imaging groups to fluorescently label azide-bearing proteins, peptides, and other biomolecules through SPAAC. Researchers commonly incorporate the reagent into workflows that require fast conjugation under conditions compatible with sensitive biological reagents, enabling downstream fluorescence microscopy, gel-based tracking, and qualitative localization studies of labeled targets. The DBCO handle provides a robust click-reactive functionality, while the BDP FL fluorophore supports direct visualization without needing additional dye coupling steps after conjugation.

2. Fluorescent Probe Construction

BDP FL DBCO is frequently employed in fluorescent probe development where a defined fluorophore-to-biomolecule linkage is required. In molecular imaging reagent pipelines, teams use the DBCO click handle to attach the BDP FL dye to azide-functional scaffolds such as targeting ligands, affinity reagents, or imaging constructs, producing conjugates for cellular imaging and binding/uptake experiments. This approach is particularly valuable when probe assembly must be streamlined to minimize handling steps and to maintain consistent labeling for comparative imaging across samples and assay batches.

3. Surface And Material Functionalization

BDP FL DBCO supports fluorescent surface engineering by enabling covalent attachment of the BDP FL fluorophore to azide-functional biomaterials and substrates. Materials scientists and biomaterials developers use the reagent to introduce stable fluorescence tags on functionalized surfaces, hydrogels, or coatings that can be monitored by fluorescence microscopy or used as visual readouts in material characterization studies. The click-reactive DBCO group allows the fluorophore to be incorporated into surface modification workflows where azide-bearing components are already present, supporting reproducible fluorescent labeling of engineered interfaces.
