BODIPY FL-X | CAS 217190-07-3

BODIPY FL-X is a BODIPY-based fluorescent dye designed for fluorescent labeling workflows, offering strong visible emission that is commonly leveraged in fluorescence microscopy and fluorescence-based assays. Its reactive functionality enables incorporation into biomolecule conjugates and labeling reagents, supporting downstream imaging and quantitative readouts where a bright, photostable fluorophore is required.

1. Fluorescent Biomolecule Labeling

BODIPY FL-X is used by chemical biology and glycobiology researchers to generate fluorescently labeled proteins, peptides, and other biomolecular conjugates for localization and binding studies. In typical workflows, the dye is incorporated into labeling constructs that are compatible with fluorescence imaging and fluorescence quantification, enabling researchers to track biomolecule distribution in solution, on surfaces, or within experimental biological systems. Because the dye is often selected for its strong emission in the visible range, it supports multiplex-friendly imaging strategies when paired with spectrally distinct fluorophores.

2. Fluorescence Microscopy Imaging

BODIPY FL-X supports fluorescence microscopy experiments where researchers need robust signal from labeled targets such as antibodies, affinity reagents, or other biomolecular probes. Imaging teams use BODIPY FL-X conjugates to visualize spatial patterns of labeled components in fixed-sample studies and to map distribution in cell-based assays where fluorescence intensity is used as a readout. The dye's bright BODIPY emission profile makes it practical for routine confocal and widefield microscopy workflows, including time-course imaging when consistent fluorescence output is required.

3. Flow Cytometry Staining

BODIPY FL-X is frequently incorporated into fluorescent staining reagents used in flow cytometry to quantify labeled biomolecules associated with cells or cell-derived materials. Researchers and assay developers use BODIPY FL-X conjugates to build fluorescence-based readouts for binding/uptake experiments, reagent screening, and characterization of labeling performance across experimental conditions. The dye's emission in the visible range aligns well with common flow cytometer filter sets used for green-channel fluorescence, facilitating straightforward integration into multicolor panels when appropriately paired with other dyes.

4. Fluorescence-Based Bioassays

BODIPY FL-X is applied in fluorescence assay development where labeled biomolecules serve as detection elements for binding assays, reagent characterization, and fluorescence readouts in microplate formats. Assay developers use BODIPY FL-X conjugates to monitor interactions and process-dependent changes by tracking fluorescence intensity from the labeled component. This makes the dye useful for constructing fluorescence standards, validating assay components, and supporting routine quantitative measurements in research laboratories that rely on plate readers or fluorescence imaging systems.
