BODIPY 558/568; bodipy-SE

BODIPY 558/568; bodipy-SE is a BODIPY-based fluorescent dye designed for labeling workflows, combining bright visible fluorescence with an activated succinimidyl ester (SE) functionality for amide coupling to primary amines. This reagent is commonly used to prepare fluorescent conjugates for fluorescence microscopy and fluorescence-based assays, where controlled dye incorporation into proteins, peptides, or other amine-containing biomolecules is required. The excitation/emission in the green-to-red range supports multicolor imaging strategies that rely on BODIPY spectral behavior and robust fluorescence readout.

1. Protein And Peptide Labeling

BODIPY 558/568; bodipy-SE is frequently used by cell biology and chemical biology laboratories to generate fluorescently labeled proteins and peptides through amine-reactive labeling of lysine residues and N-terminal primary amines. Researchers use the resulting BODIPY conjugates for tracking biomolecule uptake, monitoring binding interactions, and visualizing localization in fixed-cell and microscopy workflows. In bioconjugation workflows, the succinimidyl ester format enables straightforward incorporation of the dye into amine-rich targets, supporting downstream use in fluorescence imaging and fluorescence assay development where a stable, visible-range fluorophore is advantageous.

2. Fluorescence Microscopy Staining

BODIPY 558/568; bodipy-SE is applied as a fluorescent labeling reagent to produce microscopy-ready conjugates for cellular imaging and biomolecular staining. Imaging teams incorporate the dye into antibodies, affinity reagents, or other amine-containing probes to visualize target distribution with standard fluorescence microscopes equipped for the BODIPY excitation/emission window. Because the reagent is designed for covalent attachment to primary amines, it is commonly selected when researchers need durable staining for wash-intensive microscopy protocols and consistent signal during image acquisition. This makes it useful for mapping protein localization, studying extracellular binding events, and generating fluorescent standards for imaging experiments.

3. Flow Cytometry Conjugate Preparation

BODIPY 558/568; bodipy-SE is used in flow cytometry workflows to prepare fluorescent conjugates from amine-containing biomolecules, enabling quantitative measurement of labeled binding and cellular association. Cytometry users label proteins, peptides, or other amine-rich reagents to generate fluorescent reagents that can be added to cell suspensions for readout on flow cytometers with appropriate filter sets for the BODIPY spectral region. The SE chemistry supports covalent dye attachment, which helps maintain labeling stability during sample handling and acquisition. This approach is widely used in assay development for fluorescence-based binding studies, labeling optimization, and multicolor panel construction where BODIPY emission is a convenient spectral component.

4. Fluorescence Bioassay Development

BODIPY 558/568; bodipy-SE supports fluorescence assay development by enabling the preparation of labeled assay reagents used for monitoring binding, immobilization, or biomolecular interactions in microplate formats. Assay developers label proteins or other amine-containing components to create fluorescent reporters that can be used in endpoint fluorescence measurements and kinetic fluorescence readouts, depending on the assay design. The dye's visible fluorescence and covalent attachment via the succinimidyl ester group make it a practical choice for constructing fluorescent conjugates that must tolerate assay buffers and repeated handling. This positions BODIPY 558/568; bodipy-SE as a useful reagent for building fluorescence-based screening tools and molecular interaction assays in chemical biology and materials research labs.
