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。

>Dibenzocyclooctyne (DBCO, DBCO, ADIBO) is one of the most reactive cycloalkynes for copper-free click reaction (SPAAC, strain-promoted azide-alkyne cycloaddition). The rate of interaction of DBCO with azides is significantly higher than that of other cyclooctynes, as well as Cu-catalyzed click reaction (CuAAC). Unlike other cyclooctynes, DBCO does not interact with tetrazines, which makes it possible to use it in bioorthogonal reactions together with trans-cyclooctenes and tetrazines.
AF4568 is a bright, photostable, and hydrophilic fluorophore that emits in the orange channel. The absorption maximum is 572 nm. The emission maximum is 598 nm.
AF568 DBCO allows fluorescent labeling of azide-containing biomolecules inside living cells and whole organisms without the negative effect of copper ions on them, and inanimate samples.

Cleavage of the N-glycosyl bond between a base and its 2-deoxyribose moiety in DNA generates an apurinic/apyrimidinic (so-called abasic) site. This phenomenon, which is referred to as depurination or depyrimidination occurs spontaneously under physiological conditions.
Phosphoramidites are modified nucleosides that are used in DNA and oligonucleotide synthesis. Abasic phosphoramidite replicates the loss of base pairing ability by a nucleotide. This modification can be useful when examining DNA damage and repair.

DiA is a dialkylaminostyryl dye that fluoresces when inserted into membranes or diluted into organic solvents. DiA’s excitation max is 460 nm, and emission max is 580 nm. Due to its broad emission spectrum, DiA can be detected in the green, orange, and red channels depending on the filter used.
DiA is widely used as an anterograde and retrograde neuronal tracer in living and fixed tissues and cells. DiA 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.
DiA can be used as a second-color neuronal tracer in conjunction with other neuronal tracers, for example, DiI.

Bicyclononyne (BCN) is a stable and one of the most reactive cyclooctynes for Copper-free click chemistry. Unlike dibenzocyclooctyne (DBCO), BCN is reactive both to azides (strain-promoted azyde-alkyne cycloaddition, SPAAC) and tetrazines (inverse electron demand Diels-Alder reaction, IEDDA). Being an endo-stereoisomer, Bicyclononine in endo-BCN CE-phosphoramidite provides a higher rate of cycloaddition compared to its exo-conformer.
BCN-labeled oligonucleotides may be used for the conjugation to azide- or tetrazine-containing solid surfaces, polymers, and large proteins.
Coupling time is standard, like for amidites of natural nucleosides. Exclude the dimethoxytrityl (DMT) removal step and use the Dmt-ON protocol after amidite coupling and oxidation.
Use standard conditions for deprotection and ammonia solution, or AMA mixture (ammonium hydroxide / 40% methylamine, 1:1).

Lumizol reagent includes phenol, guanidine isothiocyanate and other components which makes the high-quality RNA extraction possible. Such components as phenol and guanidine isothiocyanate provide cell lysis and inhibit ribonucleases effectively. Thus the RNA is preserved intact.
After samples homogenization followed by the addition of chloroform the phase separation occurs: an upper, aqueous phase, the middle interphase and lower organic phase. RNA in the upper aqueous phase is then collected by precipitation with isopropanol, while DNA and proteins might be collected from the interphase and organic phase. DNA isolation from interphase and lower organic phase can be performed using ethanol solution and for proteins by precipitation with isopropanol from supernatant.

This fluorescent conjugate is useful to construct streptavidin-based fluorescent assays and visualize binding of biomolecules. This is especially useful because streptavidin has four binding centers for biotin – this gives opportunity to build different kinds of assays. For example, target molecule having affinity to surface can be conjugated with biotin and be immobilized on solid surface. After it, streptavidin can be bound to the biotinylated surface and washed. Then, bound streptavidin on the surface can be visualized with biotin-dye conjugate.
The long and hydrophilic PEG3 linker facilitates binding and decreases nonspecific interactions.

Rhodamine 6G (R6G) is a xanthene dye of rhodamine series that has been used for the labeling of oligonucleotides and DNA for quite a long time. Just like other xanthenes, R6G comes as two isomers, 5- and 6-isomer. Even though their absorption and emission spectra are virtually indistinguishable, the isomers need to be separated to avoid separation of the labeled molecules during their purification, i.e. double HPLC peaks and double spots on electrophoresis.
This is an amine reactive NHS ester derived from a pure 5-isomer of R6G. Rhodamine 6G is very bright (even used as a quantum yield standard, yield 0.95). The dye is soluble in organic solvents, such as DMF, or DMSO. They can be used as co-solvents for the labeling reactions.
罗丹明 6G (R6G) 是罗丹明系列的呫吨染料，长期以来一直用于标记寡核苷酸和 DNA。 就像其他呫吨一样，R6G 有两种异构体，5 和 6 异构体。 尽管它们的吸收和发射光谱几乎无法区分，但需要分离异构体以避免在纯化过程中分离标记分子，即在电泳上出现双 HPLC 峰和双点。
这是一种胺反应性 NHS 酯，衍生自 R6G 的纯 5-异构体。 罗丹明 6G 非常亮（即使用作量子产率标准，产率 0.95）。 该染料可溶于有机溶剂，例如 DMF 或 DMSO。 它们可用作标记反应的助溶剂。
