Labeling Chemistry
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. We offer a full spectrum of Invitrogen™ Molecular Probes™ labeling chemistries 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. Also available are tools for conjugation of biotin and other haptens to biomolecules.
Use the Molecular Probes Labeling Chemistry Selection Tool to determine the appropriate reactive dyes for your experiments.
