Fluorescents, dyes, and assays are essential tools for visualization, detection, and analysis across life science, molecular biology, and cell-based research applications. These reagents support workflows involving flow cytometry, immunofluorescence, fluorescence microscopy, live cell analysis, and multiplex assay development while helping researchers achieve reproducibility and high-quality results.
From fluorescent dye conjugation and biomolecule labeling to fluorogenic assays and viability analysis, these products are designed to support accurate detection, optimized functionality, and reliable experimental performance.
Types
Fluorescents
Fluorescents include fluorophore-based reagents used for visualization, labeling, and fluorescence detection in life science workflows. Common products include fluorescein, FITC, rhodamine, Alexa Fluor 488, Texas Red, TAMRA, and ROX dyes designed for applications involving flow cytometry, fluorescence microscopy, and live cell imaging.
These fluorescent probes are selected for properties such as excitation and emission spectra, photostability, quantum yield, and compatibility with biomolecules, including peptides, RNA, enzymes, and antibodies.
Dyes
Dyes are used for conjugation, visualization, and molecular labeling applications across immunofluorescence, IHC, and in vivo workflows. Many fluorescent dye products incorporate reactive groups such as NHS ester, maleimide, amine-reactive chemistries, biotin, or streptavidin systems for flexible conjugation and purification processes.
Available in permeable and fluorogenic formats, dyes support applications ranging from mitochondrial staining and viability analysis to multiplex imaging and fluorescent labeling kits.
Assays
Assays are designed to support quantitative and qualitative analysis in life science and molecular biology applications. These assays commonly utilize substrates, fluorogenic detection systems, quenchers, fluorophores, and antibody-based reagents for visualization and measurement workflows.
Fluorescent assay products are widely used in flow cytometry, immunofluorescence, fluorescence microscopy, RNA analysis, enzyme activity studies, and multiplex detection platforms.
