Alkyne hydrazide bifunctional linker reagent is an adapter molecule which is useful to attach terminal alkyne group to a carbonyl group of aldehydes and ketones. Carbonyl groups are encountered in proteins subjected to oxidative stress. Many small natural molecules are also carbonyl compounds. Most saccharides, as well as RNAs contain 1,2-diol fragments which can be oxidized with periodate to aldehydes, which in turn react with hydrazides.

Sulfo-Cyanine3 is a sulfated derivative of Cyanine3 dye, well soluble in water because of two negatively charged sulfo groups in its structure. By its spectral characteristics, this yellow-orange fluorescent dye is an analog of Cy™3.

Hydrazides efficiently react with aldehydes and ketones resulting in hydrazones, so this compound can be used for conjugation with carbonyl derivatives of biomolecules.

The reaction runs in aqueous conditions, which is important when working with antibodies and proteins. Cys-diol groups in sugars in glycosylated proteins and antibodies can be oxidized into dialdehydes, and cysteine in proteins can be converted with enzymes to formyl glycerol (i. e. reactive groups for conjugation with Sulfo-Cyanine3 hydrazide). Carboxyl groups of aspartic and glutamic acids in proteins and peptides can be also conjugated with Sulfo-Cyanine3 hydrazide in the presence of activating agents: carbodiimide (EDAC) or methyl morpholine (DMTMM) derivatives.

Sulfo-Cy3 是 Cy3 染料的硫酸化衍生物，由于其结构中有两个带负电荷的磺基，因此可很好地溶于水。根据其光谱特性，这种橙黄色荧光染料是 Cy™3 的类似物。

酰肼有效地与醛和酮反应生成腙，因此该化合物可用于与生物分子的羰基衍生物缀合。

反应在水性条件下进行，这在处理抗体和蛋白质时很重要。糖基化蛋白质和抗体中的糖中的 Cys-二醇基团可被氧化成二醛，蛋白质中的半胱氨酸可被酶转化为甲酰基甘油（即与磺基花青 3 酰肼结合的反应基团）。蛋白质和肽中的天冬氨酸和谷氨酸的羧基也可以在活化剂存在的情况下与磺基花青 3 酰肼结合：碳二亚胺 (EDAC) 或甲基吗啉 (DMTMM) 衍生物。

Pyrene hydrazide is a carbonyl reactive dye for the attachment of pyrene polycyclic aromatic hydrocarbon residues to aldehydes and ketones.

Pyrene is a blue-emitting fluorescent label which is especially useful as a proximity probe. When two pyrene residues are located close to each other, a longer-wavelength excimer fluorescence can be detected. Pyrene can also be FRET donor to other fluorophores. Its excited state possesses an unusually long lifetime of more than 100 ns, which allows to use this fluorophore in time-gated experiments.

Pyrene hydrazide是一种羰基活性染料，用于将Pyrene多环芳烃残基连接到醛和酮上。

Pyrene是一种蓝色荧光标记，特别适合用作邻近探针。 当两个Pyrene残基彼此靠近时，可以检测到更长波长的准分子荧光。Pyrene也可以是其他荧光团的 FRET 供体。 它的激发态具有超过 100 ns 的异常长的寿命，这允许在时间门控实验中使用这种荧光团。

Many natural and synthetic molecules contain aldehyde or ketone carbonyl groups. These carbonyls react with hydrazides with the formation of hydrazones. The reaction is spontaneous at pH values around neutral, and the resulting hydrazones are very stable.

Compounds containing 1,2-diol function, like sugars, can be oxidized with sodium periodate with the formation of carbonyl compounds for the subsequent modification with hydrazides. This is an efficient method for the labeling of glycoproteins (like antibodies), and polysaccharides.

Cyanine5.5 hydrazide is a carbonyl-reactive near infrared dye. Hydrazides quickly react with carbonyl compounds, such as aldehydes and ketones, and form stable hydrazones. This reaction is useful for the preparation of labeled conjugates.

Carbonyl groups in biomolecules can form spontaneously after oxidative stress or deamination of proteins. Alternatively, aldehyde groups can be specifically generated by periodate oxidation of sugar residues of glycoproteins, for example antibodies. Antibodies can be oxidized by sodium periodate and labeled with Cyanine5.5 hydrazide to form Cyanine5.5 labeled antibodies. Since sugar residues in antibodies are located far from variable, epitope-binding site, this method is particularly good for the labeling of antibodies.

Cyanine5.5 is a near infrared fluorophore, an analog of Cy5.5®. It is particularly suitable for the applications which require low fluorescence background. The absorption and emission wavelength of the dye exhibit significant tissue penetration, so Cyanine5.5 is suitable for in vivo NIR imaging applications.

Cy5.5 hydrazide 是一种羰基反应性近红外染料。酰肼与醛和酮等羰基化合物快速反应，形成稳定的腙。该反应可用于制备标记的偶联物。

生物分子中的羰基可以在氧化应激或蛋白质脱氨基后自发形成。或者，醛基可以通过糖蛋白（例如抗体）的糖残基的高碘酸氧化特异性地产生。抗体可被高碘酸钠氧化，并用Cyanine5.5酰肼标记，形成Cyanine5.5标记的抗体。由于抗体中的糖残基远离可变的表位结合位点，因此该方法特别适用于标记抗体。

Cy5.5 是一种近红外荧光团，是 Cy5.5® 的类似物。它特别适用于需要低荧光背景的应用。染料的吸收和发射波长表现出显着的组织穿透性，因此 Cy5.5 适用于体内近红外成像应用。
