Carboxyl coupling resin consists of 6% cross-linked agarose with covalently linked diaminodipropylamine (DADPA) to generate a free primary amine at the end of a long spacer arm. Molecules, including proteins, peptides and nucleic acids, are covalently coupled to the free primary amines, and the stable columns are ideal for affinity purification of antibodies and other interacting partners.

Dihydrorhodamine 123 is the reduced form of rhodamine 123, which is a commonly used fluorescent mitochondrial dye. It is non-fluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 123 that accumulates in mitochondrial membranes. It is useful for detecting reactive oxygen species including superoxide (in the presence of peroxidase or cytochrome c) and peroxynitrite. Dihydrorhodamine 123 dihydrochloride is functionally equivalent to dihydrorhodamine 123 but with increased stability toward air oxidation and light during storage. Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence (355/420 nm) in cells, while the oxidized form ethidium has red fluorescence (518/605 nm) upon DNA intercalation. H2DCFDA (2′,7′-Dichlorodihydrofluorescein diacetate) is a useful fluorogenic reagent to detect reactive oxygen intermediates in cells. On oxidation, H2DCFDA becomes the highly green fluorescent 2′,7′-dichlorofluorescein, 504/529 nm (end product).

Phalloidin is a toxin isolated from the deadly Amanita phalloides mushroom. It is a bicyclic peptide that binds specifically to F-actin. Fluorescent conjugates of phalloidin are convenient tools to investigate the distribution of F-actin in fixed and permeabilised cells or tissue sections. One unit (U) of phallodin is sufficient to stain one sample (200 µl staining volume). A highly selective actin filament stain for fixed and permeabilised cells. Labeled phalloidins have similar affinity for both large and small filaments.

Carbocyanine dyes with long hydrocarbon chains have low fluorescence in aqueous phase, but become highly fluorescent upon binding to lipid bilayers, making this class of dyes ideal for staining cell membranes. Carbocyanine dye membrane staining is very stable, with minimal dye transfer between cells. Dilinoleyl carbocynaine dyes have much faster lateral diffusion rates than regular carbocyanine dyes, which facilitates labelling of neurons in tissues.
