Abcam Rhodol, 5MG
MW 331.3 Da, Purity >95%. Highly fluorescent dye useful for labeling oligonucleotide, antibody and protein studies and for the preparation of peptide and esterase substrates. Rhodol is a structural hybrid of fluorescein and rhodamine. It retains the pH-sensitive properties conferred by a phenolic hydroxyl group, but the amine substituent reduces the pKa values. Rhodol exhibits a high extinction coefficient (~70,000 cm-1M-1) and high quantum yield (~0.8-0.9) in aqueous solution, with absorption maxima at approximately 490 nm and emission maxima between 520 and 545 nm. As with fluorescein-based dyes, the fluorescence excitation profiles of rhodol-based dyes are pH dependent, which can be useful for ratiometric pH determinations intracellularly.

Biotium CF800 Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Near-infrared fluorescent CF800 dye has excitation/emission at 797/816 nm.
Biotium CF568 Biocytin
Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
Biotium CF405M Protein Labeling Kit , 3x(1mg) labelings
This kit contains everything you need to label antibodies or other proteins with a fluorescent CF dye succinimidyl ester (CF dye SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Blue fluorescent CF405M dye has excitation/emission at 408/452 nm.
Biotium 5-(AND-6)-CARBOXYTetramethylrhodamine SU
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. Properties: Ex/Em (MeOH) = 540/565 nm; e = 95,000; Red solid soluble in DMF or DMSO; Store at -20°C and protect from light; C 29 H 25 N 3 O 7; MW: 527.5; [150408-83-6]
Biotium Phalloidin, CF568, 50 U
Phalloidin conjugates are actin filament stains for fixed and permeabilized cells. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 has excitation/emission at 562/583 nm.
Biotium CF770R Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red/near-IR fluorescent CF770R dye has excitation/emission at 770/701 nm.
Biotium MitoView™ 405 (Sample size)
MitoView™ 405 is a blue fluorescent mitochondrial dye for live cells. It has excitation/emission at 398/440 nm for detection in the DAPI or Pacific Blue channels. It is a replacement for our original MitoView™ Blue, with improved photostability.
