Dyes and Labeling Reagents

This category includes chemicals for permanent and temporary labeling of organells, proteins, and other molecules. This includes the covalent linkage of a target protein, for example an antibody, with a fluorescent dye / fluorophore that allows its detection in microscopic experiments. For the purpose of detection, proteins can also be labeled with reporter enzymes like HRP or radioactive isotopes. To facilitate the purification of a target protein biotinylation followed by streptavidine affinity binding has proven to be effective.
