Calcein-AM is a non-fluorescent, membrane permeable compound. Esterase activity in the cytoplasm of viable cells converts calcein-AM to the green fluorescent, membrane impermeant compound calcein, which is retained in viable cells with intact plasma membranes. The Viability/Cytotoxicity Assay kit for Animal Live & Dead Cells pairs calcein-AM with the vital dye ethidium homodimer III for quantitation of live and dead cells.

Apoptosis and necrosis are two processes by which cells die. Apoptosis is an active, regulated disassembly of the cell from within. During apoptosis, phosphatidylserine is translocated from the inner to the outer surface of the cell, allowing the dying cell to be engulfed by phagocytic cells. Annexin V is a 35 kD Ca2+-dependent phospholipid binding protein with a high affinity for phosphatidylserine.

MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.

TUNEL (terminal deoxynucleotidyl transferase (TdT) mediated dUTP nick-end labeling) is highly selective for the detection of apoptotic cells, but not necrotic cells or cells with DNA strand breaks resulting from irradiation or drug treatment. In this assay, TdT enzyme catalyses the addition of labeled dUTP to the 3’ ends of cleaved DNA fragments. Fluorescent dye-conjugated dUTP can be used for direct detection of fragmented DNA by fluorescence microscopy or flow cytometry.

Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.
