Thiol mono-reactive Cyanine3 dye. This reagent can be used to attach Cyanine3 fluorophore (an analog of Cy3®) to proteins and peptides containing cysteine residues, as well as to other thiolated molecules (such as thiol-containing oligonucleotides).
Cystines should be reduced with TCEP (tris-carboxyethylphosphine) or other appropriate reductant prior to the labeling.
Labeling with Cyanine3 maleimide is selective, and efficient.
We recommend using water-soluble Sulfo-Cyanine3 maleimide for the labeling of antibodies and other sensitive proteins.

Lumiprobe Cy5 NHS 酯 Cyanine5 NHS ester

Cy5 NHS 酯 Cyanine5 NHS ester
在过去的一些年,Cy5荧光基因是生命科学研究和诊断领域非常受欢迎的标记试剂。在红色区域有最大的荧光发射,许多CCD检测器有最大灵敏性,并且背景低。染料颜色非常深,因此即使在凝胶上少至1nmol的量用肉眼也可观察到。
Cy5 NHS酯是用来标记多肽,蛋白和寡核苷酸氨基的活性染料。此染料只需少量的共溶剂(比如DMF或DMSO)来标记反应。此试剂用来高效标记可溶性蛋白,各种多肽和寡核苷酸的氨基。对于较复杂的靶标比如易降解的蛋白,不能用DMF或DMSO时,可以考虑用水溶性sulfo-Cyanine 5 NHS 酯不需要共溶剂,并且两者有非常相似的荧光特性。
Cy5荧光基因与各种设备兼容包括许多荧光显微镜,成像仪,扫描设备和荧光成像仪等。
   Cy5 NHS酯可以替代Alexa Fluor 647, and DyLight 649和Cy3.5®活性酯。

During the last years, Cyanine5 (an analog of Cy5®) has become an incredibly popular label in life science research and diagnostics. The fluorophore has its emission maximum in the red region, where many CCD detectors exhibit maximum sensitivity, and biological objects show low background. The dye color is very intense, therefore quantities as small as 1 nmol can be detected in gel electrophoresis by naked eye.
This Cyanine5 NHS ester (analog to Cy5® NHS ester) is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. This dye requires a small amount of organic co-solvent (such as DMF or DMSO) to be used in labeling reactions (please see our recommended protocol for more details). This reagent is ideal for very cost-efficient labeling of soluble proteins as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling. For more sophisticated targets such as easily degradable proteins, when the use of DMF or DMSO is undesirable, consider using water-soluble sulfo-Cyanine 5 NHS ester which does not require any co-solvent, and features very similar fluorescent properties.

Lumiprobe 水溶性cy染料

Lumiprobe 水溶性Cy染料

磺化和非磺化染料都可用于标记生物分子例如DNA和蛋白质。染料之间的差异是它们的溶解性:磺基染料是水溶性的,并且它们不使用有机共溶剂用于在水性环境中的标记。它们不易于在水中聚集。
There are two varieties of cyanine dyes: non-sulfonated cyanines, and sulfonated cyanines. For many applications they are interchangeable, because their spectral properties are nearly identical. Both sulfonated and non-sulfonated dyes can be used for the labeling of biomolecules such as DNA and proteins. The difference between the dyes is their solubility: sulfo- dyes are water-soluble, and they do not use of organic co-solvent for the labeling in aqueous environment. They are less prone to aggregation in water.

Lumiprobe-Cyanine7 NHS ester

Lumiprobe-Cyanine7 NHS ester

胺类活性染料,近红外荧光染料,Cy7®的改进的类似物。
近红外荧光素可以被用来利用生物组织的近红外窗口。在这个光谱区域,高度增强的组织透明度使得活体成像成为可能。该染料可用于制备CY7标记的生物分子来进行后续试验,如活体研究及药物开发相关实验。
Cy7的特殊结构加固了中心聚亚甲基(polymethyne)链的稳定性。这种增强的分子结构会使其量子产率较其母结构提供20%,因此它的荧光强度会更大。
该试剂在标记时需要共溶剂有机溶剂。水溶Cy7 NHS ester可以用于蛋白NIR标记。

Lumiprobe荧光素的替代染料–菁染料

Lumiprobe荧光素的替代染料–菁染料

知识背景:

菁染料是性能优良的可代替荧光素的染料,摩尔吸光系数高,其琥珀酰亚胺酯是最常用的脂肪氨基标记试剂,广泛用于蛋白、抗体、核酸及其他生物分子的标记和检测。通过改变次甲基链的长度, 可改变其荧光发射波长,每增加一个双键,按照Huoffman 规则正好红移约100nm。

菁染料Cy3 和Cy5 已成为基因芯片的首选荧光标记物; 另外,Cy5, Cy5.5 和Cy7 的吸收在近红外区背景非常低,是荧光强度最高、最稳定的长波长染料。特别适合于活体小动物体内成像代替放射性元素。

但由于菁染料, 尤其是不对称菁染料的合成副反应多, 副产物极性相近, 产物的分离提纯相当困难。菁染料特别是水溶性菁染料分子极性大, 分离提纯越加困难。

应用领域:

 广泛应用于多肽,蛋白,核苷酸及其他生物分子的标记和检测。
