Dyes

D149 Dye is an indoline-based dye, which is a high-extinction-coefficient metal-free organic sensitizer.

Dye 937, substituted unsymmetrical cyanine dyes with selected permeability, useful in the detection of DNA in electrophoretic gels.

Dihydroethidium is a cell-permeable blue fluorescent dye.

Fluorescein biotin (FITC biotin) is a fluorescent biotin derivative and avidin and streptavidin ligand that contains a FITC fluorophore which displays excitation/emission maxima of 485/535 nm, respectively.

LDS 751 is a cell-permeable fluorescent nucleic acid dye that can be used to label double-stranded DNA (dsDNA) within live or dead cells.

L-ANAP is an unnatural amino acid with intrinsic fluorescence that can be genetically encoded into proteins.

2-NBDG is a fluorescent derivative of glucose whose uptake is competitively inhibited by D-glucose, but not L-glucose or sucrose, in E. coli.1 It has been used to monitor glucose uptake by bacteria and live mammalian cells and in tumor biopsies.

Oxazine 1 perchlorate is a symmetric cationic dye (λex=653 nm, λem=666 nm).

Monochlorobimane is a fluorescent dye (λex=380 nm, λem=470 nm).

Fluorescein di(β-D-galactopyranoside) is a fluorogenic substrate for β-galactosidase (λex=485 nm, λem=535 nm).

DiBAC4(3) is a voltage-sensitive fluorescent dye (λex=490 nm, λem=505 nm).

Di-8-ANEPPS is a naphthylstyryl voltage-sensitive dye, shifting both their fluorescence excitation and emission spectra upon changes in Vm .

6-FITC (6-Fluorescein Isothiocyanate) is a derivative of fluorescein used in wide-ranging applications including flow cytometry.

5-TAMRA (5-Carboxytetramethylrhodamine), SE and its conjugates yield bright, pH-insensitive orange-red fluorescence (approximate excitation/emission maxima ~546/579) with good photostability.

X-Gluc Dicyclohexylamine is used as a reagent to detect ??-glucuronidase, an enzyme produced by the E. Coli bacterium; is widely used in molecular biology experiments to mark and select the expression of target genes (GUS reporter system).
