Reactive CF® Dyes, Other Reactive Dyes & Biotinylation Reagents

Biotin-X-C₅-maleimide (N-(biotinoyl)-N’-(iodoacetyl)ethylenediamine) is readily and selectively coupled to thiols.

Biotin-X-DHPE (N-((6-(Biotinoyl)amino)hexanoyl)-1,2-dihexadecanoylsn-glycero-3-phosphoethanolamine, triethylammonium salt) can be used to couple avidin or streptavidin to cell membranes or liposomes.

Biotin-XX tyramide conjugate can be used for tyramide signal amplification (TSA) to generate high-density labeling of a target protein or nucleic acid with biotin.

Biotin-XX free acid (6-((6-((Biotinoyl)amino)hexanoyl)amino)hexanoic acid) can be easily converted to the mixed anhydride form, which is more reactive than the succinimidyl ester.

Biotin-XX succinimidyl ester (6-((6-((Biotinoyl)amino)hexanoyl)amino)hexanoic acid succinimidyl ester) is readily coupled to a primary or secondary amine under mild conditions. The longer XX arm facilitates the interaction between biotin and avidin or streptavidin.

BisEA (Bis-(2-(Methanethiosulfonato)ethyl)amine, hydrochloride) is a positively charged MTS cross-linker.

6-Carboxy-X-rhodamine is a single isomer, long wavelength rhodamine dye.

5(6)-ROX, SE (full name: 5-(and-6)-Carboxy-X-rhodamine, succinimidyl ester) is an amine-reactive long wavelength rhodamine dye.

5-ROX, SE (5-Carboxy-X-rhodamine, succinimidyl ester, single isomer) is the amine-reactive form of 5-carboxy-X-rhodamine single isomer.

6-ROX, SE (6-Carboxy-X-rhodamine, succinimidyl ester, single isomer) is the amine-reactive form of 6-carboxy-X-rhodamine single isomer.

5(6)-ROX [full name: 5-(and-6)-Carboxy-X-rhodamine, triethylammonium salt (mixed isomers)] is a long wavelength rhodamine dye.

5-ROX (full name: 5-Carboxy-X-rhodamine, triethylammonium salt, single isomer) is a single isomer, long wavelength rhodamine dye.

6-ROX (6-Carboxy-X-rhodamine) is a single isomer, long wavelength rhodamine dye.

For some applications, 5-(and-6)-carboxyrhodamine (5(6)-CR 110) is a superior alternative to the widely used green fluorescent dye 5-(and-6)-carboxyfluorescein. The dye is insensitive to pH between 4 and 9 and is much more photostable than fluorescein.

5-(and-6)-Carboxyrhodamine 110, SE (5-(and-6)-Carboxyrhodamine 110, succinimidyl ester, mixed isomers), also known as Carboxyrhodamine 110-NHS, is a superior green fluorescent dye that readily reacts with primary or secondary amines.

Amine-reactive form of single isomer carboxyrhodamine 110, useful in DNA sequencing. For many single-dye-labeling applications, the dye is preferred over other green fluorescent dyes including fluorescein and Alexa Fluor® 488 because of its exceptional photostability and fluorescence insensitivity to pH.
