CellTrace™ calcein red-orange AM	C34851	576/589		Intrinsically fluorescent; a useful cell tracer and indicator of cell viability; can be used in combination with blueand green-fluorescent probes
CellTrace™ Far Red DDAO-SE	C34553	646/659 (pH-dependent spectra; values determined at pH 9)		A fixable, far red–fluorescent tracer for very long-term cell labeling; the succinimidyl ester (SE) reactive group forms a strong covalent attachment to primary amines that occur in proteins and other biomolecules on the inside and outside of cells
