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.

CF(R)750 Tyramide
CF(R)750 Tyramide

Item number: BOT-96052

CF(R) dye tyramide conjugates can be used for tyramide signal amplification (TSA), which is an enzyme-mediated detection method that uses horseradish peroxidase (HRP) to generate high-density labeling of a target protein or nucleic acid in situ. CF(R) dyes are Biotium's line of next-generation fluorescent dyes with...

Ethidium Homodimer I, 2 mM in DMSO
Ethidium Homodimer I, 2 mM in DMSO

Item number: BOT-40014

Ethidium Homodimer I, first developed by Dr. Le Pecq and his colleagues, is a high affinity fluorescent nucleic acid stain. It binds to both DNA and RNA in a sequence-independent manner and with a >,30-fold fluorescence enhancement. The DNA binding of each Ethidium Homodimer covers four base pairs and is believed...

CF(R)488A Biocytin
CF(R)488A Biocytin

Item number: BOT-92004

Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during...
