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.

(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】:

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。

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)}

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)}

Lumiprobe BDP FL NHS ester CAS 146616-66-2

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 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.
