Water soluble Cyanine 5 succinimidyl ester (SE), an equivalent of Cy5® NHS ester, for the labeling of various amine-containing molecules in aqueous phase without use of any organic co-solvent. This product is therefore particularly useful for the labeling of proteins which denature in the presence of organic co-solvents, as well as for proteins with low solubility.

Sulfo-Cyanine 5 is an analog of Cy5®, one of the most popular fluorophores which is compatible with various equipment such as plate readers, microscopes, and imagers.

This dye is highly hydrophilic and water-soluble. A non-sulfonated analog is also available.

Can be used as a replacement for Cy5®, Alexa Fluor 647, DyLight 649 for all applications.

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.

Cy3/5/7 NHS ester和带NH2多肽和抗体连接实验方法及步骤

Cy3 NHS ester, Cyanine5 NHS ester和Cyanine7 NHS ester可以标记含有amine的多肽，抗体，蛋白，DNA和寡核苷酸及其他小分子。在反应条件下NHS可以和NH2发生反应，从而连接到一起。

（一）：Cyanine5 NHS ester和多克隆抗体的连接实验方法和步骤

【准备材料】：

Cy3 NHS ester purchased from xi an ruixibio

anti-GST多克隆抗体purchased from Abcam

【实验步骤】：

1.      在1 L 0.15 M NaCl 溶液中透析anti-GST抗体(浓度为 0.5 mL at3 mg/mL)，常温透析4小时。

2.      在4°C用新鲜的1 L 0.15 M NaCl 溶液再透析过夜。

3.      第二天用1 L 0.1 M NaHCO3 (pH 8.3)透析4小时。

4.      用0.22 μm注射器过滤头过滤抗体溶液。

5.      用0.1 M NaHCO3 稀释少量的抗体，在280nm处测其紫外吸收值计算标记抗体的总量 (IgG antibody摩尔吸光系数170 000 M-1 cm-1 at 280 nm).

6.      用DMSO配置Cy3 NHS (MW 616.19)溶液浓度为10 mg/mL;计算所需体积以得到想要的Cy3NHS 和抗体的比值(例如20:1)，然后慢慢将其加入到抗体溶液中，同时在暗处常温缓慢搅拌45分钟。

7.      用1 L 0.15 M NaCl 溶液常温避光透析4小时除去未标记上的Cy5。

8.      在4°C用新鲜的1 L 0.15 M NaCl 溶液再避光透析过夜。

9.      用1 L of 0.01 M PBS/ 0.01% 叠氮化钠溶液常温避光透析4小时, 在4°C常温避光再次透析过夜。

10.  用0.22 μm注射器过滤头过滤抗体溶液。

11.  用0.01 M PBS/0.01 % 叠氮化钠整数倍稀释标记抗体溶液，测量280nm(蛋白)和552nm(Cy)处的紫外可见吸光度。

12.  产品冷冻干燥成粉末或在0.01 M PBS/ 0.01% 叠氮化钠溶液中，-20℃避光储存。

F/P计算：

Cy3在552nm摩尔吸光系数为150 000M-1 cm-1;此蛋白在280nm的摩尔吸光系数为170 000 M-1 cm-1;

不同蛋白的摩尔吸光系数不一样;.Cy3染料本身在280 nm 的吸收是552nm处的8%。按以下公式计算F/P

值。

[Cy3] = A552/150000

[antibody] = {A280 – (0.08×A552)}/170000

F/P final= [Cy3]/[antibody]= {1.13×A552}/{A280 – (0.08×A552)}

（二）：Cyanine5 NHS ester和标记 (D-ser2)-leucineenkephalin的连接实验方法和步骤

【准备材料】：

Cy5 NHS ester purchased from xi an ruixibio

(D-ser2)-leucineenkephalin purchased fromsigma

【实验步骤】：

1.      Cy5 NHS 1.0 mg 溶解于400 μL DMSO后，加入到1mL 的玻璃瓶中盛有(D-ser2)-leucine-enkephalinacetate(YSGFLT, 0.75 mg) 的400 μL DMSO溶液。(Dye 和peptide 投料比是 1:1)

2.      然后加入15 μL三乙胺，常温避光搅拌反应混合物过夜。

3.      用HPLC 纯化蛋白，使用蛋白C18柱子(25 cm×10 mm)，每次上样注入2×400 μL，30分钟梯度洗脱从0.1% TFA水溶液到MeCN∶H2O(0.1% TFA)=70∶30，流速4mL /min。(对不同的蛋白选择不同的合适HPLC梯度流动相)

4.      收集适当的色带峰，标记多肽的保留时间比未标记的多肽长。

5.      产品冷冻干燥成粉末或在水溶液中，-20℃避光储存;必要时可用质谱表征。

6.      CyDye标记的蛋白稳定性取决于蛋白本身。例如标记的IgG在4 ℃可避光保存2月;更长期的保存需加入等体积的甘油-20 ℃避光保存.

F/P计算：

Cy5 在650 nm 的摩尔吸光系数为250 000 M-1 cm-1 ，所用蛋白在280 nm处的摩尔吸光系数为 170

000 M-1 cm-1;Cy5在280nm处的吸收是650nm处的5%。按以下公式计算F/P值。

[Cy5 dye] = (A650)/250 000

[peptide] =[A280 -(0.05×A650)]/170 000

F/P final= [dye]/[peptide]= {0.68×A650}/{A280 – (0.05×A650)}

BDP FL NHS ester is an advanced dye for 488 nm channel, a replacement for fluorescein, a molecule identical to BODIPY FL® NHS ester. An amino-reactive dye for the labeling of proteins and peptides.

While the absorbance and emission spectra of this molecule stay within FAM excitation and emission channels, this dye provides much better photostability, and outstanding brightness. The fluorescence spectrum of BODIPY-FL is narrower than that of FAM. This provides a better brightness for monochromator based instruments, when emission wavelength can be tuned to dye maximum.

The dye is neutral, possesses low molecular weight, and retains high quantum yield in conjugates.

The dye is a good replacement for fluorescein (FAM), BODIPY-FL, Alexa Fluor 488, DyLight 488, Cy2, and other 488 nm dyes.

Bodipy(BDP)氟硼荧光活性染料发展历史

Bodipy二吡咯类荧光染料相对比于荧光素、罗丹明或者菁染料有着较高的选择性、高灵敏度、高荧光量子产率、高摩尔消光系数、良好的光学稳定性和对PH不敏感的优点被广泛应用于生物标记、荧光探针及生物成像，西安瑞禧生物科技有限公司可以提供种类丰富的Bodipy荧光染料，荧光波长可定制 从550-800之间，末端可以修饰各种活性基团。

Bodipy类荧光染料具有良好的稳定性、优良的光学性能，主要表现在以下几个方面：

1：BODIPY的光谱峰宽比较窄，在光学领域和生物学领域进行分析检测时，光谱峰宽较窄，检测灵敏度较高，并且减少了待测样品的用量。测得的结果中，荧光光谱上会出现更为明显的荧光吸收和发射的变化，这样更精确地测得了样品的含量。

2：在整个BODIPY分子中，并不存在负电荷。因而在溶液中，溶液中的离子无法与缺少电荷的BODIPY分子发生静电作用，这样非常有效的避免了测定时静电作用对测量结果的干扰，使测定过程更加稳定，测得结果更加精准。

3：BODIPY类荧光染料的光稳定性能非常优越，当它被激发到达激发态时，不会因为很长时间的激发而在分析测定过程中发生激发态的分解或其他变化，这样测得的荧光光谱更加准确可信。

4：BODIPY染料，其荧光量子产率甚至接近1.0。一般普通的染料在水溶液中其荧光量子产率会变低，有的甚至被猝灭。对于BODIPY分子来说，在水溶液中其荧光量子产率虽然有所下降，但它仍然能保持较高的荧光量子产率。

5：由BODIPY的母体结构可知，他的母体结构上的取代基一般不会出现氨基或羧基这类对酸碱敏感的活性基团。因此外界的酸碱度对其影响会大幅度减小，因此BODIPY染料不会轻易变质。

6：BODIPY类荧光染料对光的感应度很高，并且它还有高的摩尔消光系数，有些经过修饰后的BODIPY染料在水溶液中的溶解度也较高，再加上它在水中不易被猝灭这一优异的性能，使得BODIPY在光学、生物学、分析学领域有着极其广泛的应用。

BODIPY母体结构最初是由德国化学家Treibs, A.和kreuzer, F. H.在1968年合成的，他们合成的BODIPY 类荧光染料 [40] 。另外，他们还合成了BODIPY染料的母体结构。在BODIPY母体结构中，Treibs, A.和kreuzer, F. H.在R1-R7中用不同基团取代得到不同的衍生产物。人们根据Treibs, A.和kreuzer, F. H.的前期探索，对BODIPY类染料做出了多种结构修饰，这大大丰富了BODIPY的种类，使其迅猛发展。

Lumiprobe BDP TR X NHS ester

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

BDP TR is a borondipyrromethene dye which has absorption and emission wavelengths close to Texas Red (ROX) dye. The fluorophore is bright, moderately hydrophobic, and has low molecular weight. An extra linker based on aminocaproic acid (C6) provide better separation between the dye, and the biomolecule.

The NHS ester function can be used for the conjugation with proteins, peptides, and other molecules possessing amine group.

Lumiprobe Perylene azide荧光染料

Lumiprobe Perylene azide荧光染料

Perylene是一种高亮度的且对公极其稳定的多环芳烃（PAH）类荧光染料，其量子产率接近理想化。
因其很短的荧光期，这种探针没有激发态。
因其较低的溶解度和很少量的活性衍生物，Perylene标记生物分子通常比较困难且不太容易实现。然而，通过点击化学使用这种perylene azide来进行标记就变得和其他染料一样非常容易。使用这种多环芳烃染料标记多肽、DNA、蛋白等从未如此轻松。
为了提高其亲水性和标记成功率，这种PAH azide包含亲水三甘醇链。

Perylene is a bright and extremely photostable fluorescent polycyclic aromatic hydrocarbon (PAH) label with quantum yield approaching quantitative.

Due to low life time of fluorescence, this probe does not form excimers.

Perylene labeling of biomolecules is used to be difficult and tedious because of low solubility of perylene, and low availability of activated derivatives. However, labeling via Click Chemistry with this perylene azide is nearly as easy, as with other dyes. Labeling peptide, DNA, protein with this polyaromatic hydrocarbon has never been so simple yet.

To increase hydrophilicity, and facilitate labeling, this PAH azide contains hydrophilic triethyleneglycol linker.

Lumiprobe Sulfo-Cyanine3 azide

Sulfo-Cyanine3 azide是用于点击化学的水溶叠氮染料。其激发和发射波长与Cy®荧光团相同。
由于这种染料的高亮度，耐光性，再加上在水中高溶解度的特点，该染料成为点击化学中水相标记各种分子的理想选择。
在水相中不需有机共溶剂即可进行点击反应（Click reaction）。该染料是为标记敏感的分子如蛋白甚至完整的生物体而设计。
该试剂是1:1混合的crystallosolvate和methanol。但不会对荧光团性能和应用有任何影响。

Sulfo-Cyanine3 azide is a water-soluble dye azide for Click Chemistry. Absorbance and emission of the dye are identical to Cy3® fluorophore.

Brightness and photostability of fluorophore, together with high water solubility, makes this reagent an ideal choice for Click chemistry labeling of various molecules in aqueous phase.

Click reaction can be carried out in pure water without need to use organic co-solvent. The reagent is designed for the labeling of sensitive molecules such as proteins, and even intact biological objects.
