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.

5-dR110 [5-Carboxy-4,7-dichlororhodamine 110]
5-dR110 [5-Carboxy-4,7-dichlororhodamine 110]

Item number: ABD-315

Compared to fluorescein labeling reagents such as FITC and FAM, 5-dR110 [5-carboxy-4,7-dichlororhodamine 110] reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength. They are photostable alternative reagents superior to FITC...

FMOC-Glu(biotinyl-PEG)-OH
FMOC-Glu(biotinyl-PEG)-OH

Item number: ABD-5027

This PEG biotin-labeled amino acid has excellent solubility in DMF and other solvents used in SPPS. It is an excellent alternative to FMOC-Lys(biotin)-OH (#5020) due to its improved solubility in both organic solvents and water. In addition, the PEG-spacer reduce the hindrance between the target peptide and avidin,...
