FM4-64 (SynaptoRedTM C2) is a styryl dye that stains stably but does not fluoresce in aqueous solution.FM4-64 does not passively diffuse into the plasma membrane bilayer and must be actively transported across the membrane.FM4-64 can be used to study cytotoxicity, cytosolization, and vesicular transport.Cephalexin monohydroxylin monohydroxylin (Cephalexin monohydroxylin) can be used to study cytotoxicity and vesicular transport.

DiI (DiIC18(3)) is a lipophilic membrane dye commonly used as a long-term tracer for neurons and other cells. DiI fluoresces very weakly before it enters the cell membrane, and only after it enters the cell membrane can it be excited to emit a strong orange-red fluorescence (λex=549 nm, λem=565 nm).

DiO (DiOC18(3)) is a fluorescent lipophilic tracer and can be widely used to label cells, organelles, liposomes, viruses, and lipoproteins.

DiD perchlorate is a lipophilic cyanine dye.

Laurdan (6-Dodecanoyl-2-dimethylaminonaphthalene) is a fluorescent membrane probe that is spectrally sensitive to the phospholipid phase of the cell membrane to which it binds.

TMA-DPH, a hydrophobic fluorescent membrane probe (Ex: 355 nm; Em: 430 nm), is used for studying membrane dynamics and structure.

DiR iodide (DiR iodide [1,1'-dioctadecyl-3,3,3',3'-tetramethylindotricarbocyanine iodide]) is an important near infrared (NIR) fluorescent dye, which has been widely used for in vivo monitoring of cells.

Octadecyl Rhodamine B chloride, also known as RBOE, is a polarity-sensitive dye that is often used as a chromophore with other compounds to stain cell membranes and has applications in the assembly of organic molecules, in membrane structures and in the transfer of electron energy in the structural domains of proteins.

TMRM is a cell-permeant cationic lipophilic red fluorescent dye (λex: 530 nm, λem: 592 nm).

7-Methoxycoumarin-3-carboxylic acid may be used as a reference compound in the purification, separation and analysis of coumarin compounds.

para-iodoHoechst 33258 is part of a family of blue fluorescent dyes used to stain DNA. Hoechst 33258 is a cell dye for DNA quantitation.

Prodan, a solvatochromic fluorophore, serves as a sensitive reporter for microenvironment changes in membranes. Utilizing Prodan's chemistry, researchers have designed and synthesized fluorescent nucleosides that exhibit a sensitive variation in their Stokes shift values, reflecting the orientational polarizability of the solvent.
