DCC0967	HCQ-2 NHS	HCQ-2 NHS is a dark quencher with no native emission due to the polyaromatic-azo backbone and a terminal NHS ester. UBHQ-2 NHS has a wide and intense quenching range from 560-670 nm, which makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with orange to far-red emitting dyes. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
DC47813	OG 488, acid	OG 488, acid, a fluorescent pH indicator, has many applications in biochemistry and neurosciences.
DC41285	TFAX 488,SE dilithium	TFAX 488,SE dilithium, an amine reactive green fluorescent dye, is insensitive to pH in the range 4-10. TFAX 488,SE dilithium forms bright and photostable conjugates with proteins and antibodies. TFAX 488,SE dilithium is suitable for use in flow cytometry, two-photon excitation microscopy (TPE), and super resolution microscopy techniques, such as dSTORM, SIM and STED. Excitation maximum=495 nm; emission maximum=515 nm; extinction coefficient=73,000 M-1cm-1; quantum yield=0.92.
