Reactive CF® Dyes, Other Reactive Dyes & Biotinylation Reagents

5(6)-ROX maleimide has C6-linker that enhances the fluorescence after the dye is conjugated to proteins. The product is a direct replacement of 5(6)-carboxy-X-rhodamine C5-maleimide (91041).

6-ROX, SE is the amine-reactive form of 6-ROX single isomer (90037) dissolved in anhydrous DMSO, suitable for labeling oligonucleotides.

5-ROX-PEO₈ SE (full name: 5-Carboxy-X-rhodamine-PEO₈-propionate, succinimidyl ester) has an approximately 32 Angstrom water-soluble PEG spacer that separates the red fluorescent ROX dye and the amine-reactive SE group.

5(6)-SFX has a 6-atom aminohexanoyl spacer group that separates the fluorescein dye and the amine-reactive group.

5-SFX has a 6-atom aminohexanoyl spacer group that separates the fluorescein dye and the amine-reactive group.

6-SFX has a 6-atom aminohexanoyl spacer group that separates the fluorescein dye and the amine-reactive group.

Sulforhodamine 101 cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.

Sulforhodamine 101-PEO₃-amine has a long water-soluble spacer separating the dye and the amine group. The dye can be coupled to activated carboxy groups or sulfonyl chlorides.

SR101-PEO₁₂ SE (Sulforhodamine 101-PEO₁₂-propionic acid succinimydyl ester; Texas Red®-PEO₁₂ SE) has an approximately 47 Angstrom water-soluble PEG spacer that separates the dye from the amine-reactive SE group.

SR101-PEO₈ SE (Sulforhodamine 101-PEO₈-propionic acid succinimydyl ester; Texas Red®-PEO₈ SE) has an approximately 32 Angstrom water-soluble PEG spacer that separates the dye from the amine-reactive SE group.

Tetramethylrhodamine (TAMRA) cadaverine (full name: 5-(and-6-)-((N-(5-Aminopentyl)amino)carbonyl)tetramethylrhodamine) can be coupled to activated carboxy groups or sulfonyl chlorides.

Mixed isomers of carboxytetramethylrhodamine (TAMRA) free acid. The dye can be coupled to primary or secondary amines via standard peptide chemistry.

5(6)-TAMRA SE (full name: 5-(and-6)-Carboxytetramethylrhodamine succinimidyl ester (mixed isomers)) is the amine reactive form of TAMRA, one of the most commonly used red fluorescent dyes. The succinimidyl ester reacts readily with primary or secondary amines under mild conditions.

Full name: 5-Carboxytetramethylrhodamine succinimidyl ester (single isomer). Amine-reactive form of carboxytetramethylrhodamine (TAMRA) single isomer.

6-TAMRA SE (full name: 6-Carboxytetramethylrhodamine succinimidyl ester) is the amine-reactive form of 6-TAMRA single isomer (90035).

Full name: 6-Carboxytetramethylrhodamine succinimidyl ester single isomer. Amine-reactive form ofcarboxytetramethylrhodamine (TAMRA) single isomer.
