Dyes and Labeling Reagents

This category comprises chemicals for permanent and temporary labeling of organelles, proteins, and other molecules. For example, this includes the covalent linkage of a target protein, such as an antibody, with a fluorescent dye/fluorophore, allowing detection of the target protein in microscopic experiments. For the purpose of detection, proteins can also be coupled with reporter enzymes (e.g. HRP) or radioactive isotopes. To facilitate the purification of a target protein, biotinylation followed by streptavidine affinity binding has proven to be effective.

MitoDNA(TM) Red 610
MitoDNA(TM) Red 610

Item number: ABD-22687

Excitation (nm): 508. Emission (nm): 607. There are very few probes that can be effectively used to detect mitochondrial deoxyribonucleic acid (mtDNA). The common fluorescent DNA probes (such as DAPI, Hoechst or SYBR(R) Green) lack the specificity to target mitochondria. They predominantly stain nuclei. MitoDNA(TM)...

CF(R)640R DBCO
CF(R)640R DBCO

Item number: BOT-96116

CF(R) 640R DBCO (Dibenzocyclooctyne) is a highly efficient, fast-reacting alternative to fluorescently labeled BCN and DIBO. DBCO-azide reactions do not require toxic copper catalysts (CuAAC), making them more suitable for live-cell or in vivo experiments.
