LDS 867 | CAS 106025-71-2

LDS 867 is a fluorescent dye used as a molecular imaging and labeling reagent in chemical biology workflows, where its emission properties and dye stability support visualization of labeled targets in microscopy and fluorescence-based assays. In many research settings, LDS 867 is handled as a convenient fluorophore for conjugate preparation and for tracking biomolecule or material-associated processes during assay development and analytical characterization.

1. Fluorescence Microscopy Labeling

LDS 867 is commonly used by cell biology and materials research groups to generate fluorescent labeling reagents for imaging experiments, including tracking labeled biomolecules and monitoring fluorescence-tagged constructs in adherent cell preparations and microscopy samples. Researchers incorporate LDS 867 into labeling strategies for fixed or prepared specimens to visualize spatial distribution of the labeled component using standard epifluorescence and fluorescence microscopy workflows, supporting qualitative localization studies and co-localization experiments when paired with spectrally compatible fluorophores.

2. Fluorescent Bioassay Tracing

LDS 867 is frequently selected for fluorescence-based bioassay development and analytical tracing, where a stable dye signal enables monitoring of labeled reagents during assay workflows. In practice, teams use LDS 867 to follow the incorporation or retention of fluorescently tagged biomolecules in binding studies, wash-dependent assay formats, and fluorescence readout experiments, leveraging its role as a labeling fluorophore to generate measurable signal outputs for method development and reagent screening.

3. Conjugate Preparation For Research

LDS 867 is used by chemical biology and bioconjugation researchers as a fluorophore component for preparing fluorescent conjugates that can be introduced into downstream experiments, including studies requiring defined fluorescent labeling of proteins, peptides, or other research-grade biomolecular constructs. The dye's utility in conjugate preparation supports workflows where researchers need a consistent fluorescent tag for imaging, quantification, or comparative evaluation of labeled materials across experimental conditions.

4. Flow Cytometry Fluorescent Tagging

LDS 867 is applied in flow cytometry workflows as a fluorescent label for quantifying fluorescence-associated populations when the dye's spectral characteristics align with available instrument channels. Researchers use LDS 867-labeled conjugates to assess relative labeling levels on prepared samples, supporting comparative studies of reagent binding, uptake, or surface association in suspension-based experimental formats.
