TechnoDye 498/505 | CAS 105237-27-2

TechnoDye 498/505 is a fluorescence dye engineered for blue-green excitation with emission centered near 505 nm, making it a practical choice for multicolor labeling and fluorescence readouts in standard epifluorescence and fluorescence plate formats. Its use in research workflows is driven by the ability to generate bright, easily detected signals when conjugated to biomolecules or incorporated into labeling reagents for microscopy and assay development.

1. Fluorescence Microscopy Labeling

TechnoDye 498/505 is used by cell biology and microscopy groups to visualize labeled biomolecules in fixed-cell imaging workflows and fluorescence microscopy experiments where emission near 505 nm provides clean separation from longer-wavelength channels. Researchers typically incorporate the dye into fluorescent conjugates for tracking binding partners, following localization patterns, or generating contrast in imaging studies that rely on filter sets compatible with the dye's blue-green excitation and green emission window. The dye's small-molecule fluorescence format also supports routine labeling workflows for preparing imaging reagents used in academic and industrial screening laboratories.

2. Flow Cytometry Fluorescent Tagging

TechnoDye 498/505 supports flow cytometry dye panels where a green-emitting reporter in the ~505 nm region is needed to quantify labeled targets by fluorescence intensity. In common cytometry workflows, the dye is used as a fluorescent tag on antibodies, affinity reagents, or other labeling constructs to enable rapid single-cell analysis in multiplex experiments, including studies that compare marker expression across experimental conditions. Its emission positioning in the green channel region helps researchers design instrument-ready staining schemes that minimize spectral overlap with red-shifted reporters.

3. Fluorescence Bioassay Reporter

TechnoDye 498/505 is frequently selected for fluorescence-based bioassays and reagent development where a stable, readily measurable green emission signal is advantageous for plate reader or cuvette-based detection. Assay developers use the dye as a reporter in labeling strategies that generate measurable fluorescence outputs for binding assays, reagent characterization, and screening formats that require consistent signal generation. The dye's spectral placement supports assay multiplexing strategies in which a ~505 nm emission channel is reserved for a specific readout while other reporters occupy different spectral regions.

4. Fluorescent Conjugate Standards

TechnoDye 498/505 is also employed as a fluorescence standard component for method development and assay optimization, where researchers need a defined fluorescent signal to evaluate staining consistency, imaging exposure settings, or detector response across experimental runs. In fluorescence chemistry and molecular imaging workflows, the dye can be used to prepare calibration materials or reference conjugates that help laboratories align instrument settings and compare relative fluorescence outputs between batches. This use is particularly common in environments that run routine fluorescence measurements for labeling reagent qualification and imaging protocol tuning.
