Conventional fluorescent dyes represent fundamental optical probes designed for reliable detection and visualization in biological research and diagnostics. Our comprehensive portfolio includes fluorescein, rhodamine, and cyanine derivatives, delivering consistent fluorescence output with quantum yields of 0.3-0.9 and optimal photostability for standard experimental durations.
 

Key applications encompass:

• Cellular Imaging - High-contrast labeling for microscopy and histology
• Flow Cytometry - Multiplexed cell population analysis with stable emission profiles
• Molecular Diagnostics - Robust conjugates for immunoassays and nucleic acid detection

Engineered with versatile reactive groups (-COOH, -NH2, -SH), these dyes facilitate straightforward conjugation to antibodies, proteins, and oligonucleotides. Their well-characterized spectral properties and decades of application history make them indispensable tools for routine laboratory workflows and diagnostic test development.
