DiO, also called DiOC18(3), is a green fluorescent, lipophilic carbocyanine dye. DiO’s excitation max is 484 nm, and emission max is 501 nm.

DiO is widely used as an anterograde and retrograde neuronal tracer in living and fixed tissues and cells. DiO uniformly labels neurons via diffusion in the plasma membrane. In intact tissue, the dye does not transfer from labeled to unlabeled cells but some transfer may occur when the membrane is disrupted, for example after sectioning.

DiO and DiI are often used together in dual-color studies. But DiO has a slower lateral diffusion rate on the membranes than that of DiI.

DiO，也称为 DiOC18(3)，是一种绿色荧光、亲油性羰花青染料。DiO 的最大激发波长为 484 nm，最大发射波长为 501 nm。

DiO 被广泛用作活的和固定的组织和细胞中的顺行和逆行神经元示踪剂。DiO 通过质膜中的扩散均匀地标记神经元。在完整组织中，染料不会从标记的细胞转移到未标记的细胞，但当膜被破坏时，例如在切片后，可能会发生一些转移。

DiO 和 DiI 在双色研究中经常一起使用。但 DiO 在膜上的横向扩散速率比 DiI 慢。

DusQ3 is a dark quencher for far red and near infrared fluorophores, especially suitable for Cyanine5.5.

The dye can be attached to 3′-terminus of oligonucleotides by means of automated solid phase synthesis using this support. The dye is sensitive to nucleophilic reagents, and therefore must be carefully deprotected. We recommend the use of ultramild, phenoxyacetyl protected monomers. As an alternative, post-synthetic labeling using NHS ester of the quencher can be used.

DMF (dimethylformamide) is a recommended solvent for labeling reactions using NHS esters. However, when DMF is stored in air, it deteriorates slowly absorbing moisture, and releasing dimethylamine. These impurities rapidly destroy NHS ester function, decrease labeling efficiency, and even make labeling reaction fail.

AF488 is a fluorescent dye. AF488 is a fluorophore pH-insensitive over a broad pH range (from 4 to 10). It has an absorption maximum at 495 nm and an emission maximum at 519 nm in the green spectrum region. The dye is hydrophilic and can be used to introduce the fluorescent label into various molecules, including proteins and antibodies. Conjugates of molecules with AF488 have high brightness and photostability and are commonly used in flow cytometry and microscopy. This allows the detection of biological objects with high sensitivity at a longer imaging time.

AF488 azide interacts with alkynyl derivatives of biomolecules in Click Chemistry reactions either in the presence of copper (I) catalyst (with terminal alkynes) or without catalyst (with cyclooctynes), leading to the formation of stable adducts.

Pyrene is a polyaromatic hydrocarbon which exhibits fluorescence in blue range of the spectrum. When two pyrene residues are closely spaced, excimer fluorescence is observed at longer wavelength. Therefore, pyrene is useful as a proximity label.

Pyrene exhibits affinity to graphite, and can be used as an anchor group for graphite. This reagent can be conjugated with biomolecules for their subsequent immobilization on graphite surfaces.

This NHS ester allows to label biomolecules with amino groups, such as proteins, peptides, amino-DNA and other molecules.

Pyrene is also a FRET donor for perylene.
