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.

Biotin-azide
Biotin-azide

Item number: Cay13040-1

Biotin-azide is a form of biotin with a terminal azide group. It is used to add biotin to other molecules that bear either an alkyne group, through click chemistry, or a phosphine group, using Staudinger ligation. Biotin-azide has been commonly used to biotin-tag alkynylated lipids, particularly those associated...

2',7'-Dichlorofluorescein diacetate
2',7'-Dichlorofluorescein diacetate

Item number: CDX-D0064-M050

Dichlorofluorescin diacetate (H2DCFDA) is a chemically reduced analog of fluorescein, used as an indicator for reactive oxygen species (ROS) in cells. The cell permeable non-fluorescent H2DCFDA is cleaved by cellular esterases and oxidation, and converted to the highly fluorescent 2',7'-dichlorofluorescein. H2DCFDA...
