FD-1080 free acid, an NIR-II region fluorophore (Ex=1064 nm, Em=1080 nm), facilitates in vivo imaging [1].

FD-1080 is a fluorophore that exhibits both excitation and emission in the NIR-II region, making it suitable for in vivo imaging.

FD&C Yellow No. 4 is a dye.

Tartrazine (Acid Yellow 23) is a food additive that belongs to a class of artificial dyes and contains an azo group; it has significant genotoxic effect , may be harmful to health and its prolonged use could trigger carcinogenesis.

Brilliant Blue FCF (Erioglaucine disodium salt) is a nontoxic dye for saphenous vein graft marking that abrogates response to injury.

6-CFDA N-succinimidyl ester (Carboxyfluorescein diacetate succinimidyl) is capable of spontaneously and irreversibly binding to free amines. Utilized in flow cytometry experiments for tracking cell division in both mammalian cells and bacteria. Used in combination with several cell permeabilizers as an effective, nondestructive fluorescencent stain to quickly detect bacterial cells.

C12FDG (5-Dodecanoylaminofluorescein di-beta-D-Galactopyranoside) is used as a lipophilic green fluorescent substrate for detecting beta-galactose activity, a green fluorescent substrate, is a senescence marker and is often used in conjunction with flow cytometry.

Fast Green FCF (FD&C Green No. 3), a safe biocompatible color additive, has been suggested to mitigate chronic pain.

H2DCFDA (DCFH-DA) belongs to the class of green fluorescent dyes and is a probe for the detection of intracellular reactive oxygen species (ROS) (Ex/Em=488/525 nm) with cell membrane permeability.

6-CFDA (6-Carboxyfluorescein diacetate) is fluorescent polyanionic probe that used to measure changes in intracellular pH (pHi) and processes such as dendrimer aggregation and absorption.

5-CFDA-AM is a cell-permeable esterase substrate used as an active probe to evaluate enzyme activity and cell membrane integrity. Electroneutral and able to enter cells at lower concentrations than CFDA, it undergoes intracellular hydrolysis by esterases to produce carboxyfluorescein, which possesses an extra negative charge, enhancing cellular retention [1].

CMFDA can be used as a fluorescent whole-cell-tracking reagent.

5(6)-CFDA (5-(6)-Carboxyfluorescein diacetate) is a cell-permeant esterase substrate that can serve as a viability probe that measures both enzymatic activities, which is required to activate its fluorescence, and cell-membrane integrity, which is required for intracellular retention of their fluorescent product.

5-CFDA (5-Carboxyfluorescein diacetate)(5-Carboxyfluorescein diacetate) is membrane-permeant. It can be loaded into cells via incubation and hydrolyzed by intracellular esterases to 5-carboxyfluorescein that is used for labeling human intervertebral disk cells in vitro for fluorescence microscopy.

CM-H2DCFDA is a fluorescent indicator for reactive oxygen species (ROS) in cells.

FD&C Blue No. 1 aluminum lake is an agent of dye.

FD&C Yellow No. 5 Aluminum Lake is a synthetic lemon yellow azo dye primarily used as a food coloring.
