LiFluor™ Fluorescent Dyes
Fluorescent labeling of biomolecules enables researchers to detect specific components of complex biological assemblies with exquisite sensitivity in applications ranging from imaging and flow cytometry, to Western blots. LifeSct offers a full spectrum of LiFluor™ Dyes for labeling antibodies, proteins, peptides, ligands, synthetic oligonucleotides and other biomolecules for use with immunochemistry, fluorescence in situ hybridization (FISH), cell tracing, receptor labeling, and cytochemistry applications as well as probing biological structure, function and interactions. LifeSct offers a series of superior bright, highly photo-stable and excellent water-soluble LiFluor™ dyes spanning the visible and near-infrared (IR) spectrum for labeling biomolecules, especially proteins and nucleic acids.
