一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Cyanine3.5 NHS ester is a dye for labeling of oligonucleotides, peptides and proteins which contain amino-groups. For fluorescence imaging and other fluorescence-based biochemical analysis, it has been used to label biological molecules too. Cy3.5 dyes have enhanced fluorescence upon binding to proteins. The excitation peak and emission peak of Cy3.5 dye is around 550nm and 590nm respectively. Most derivatives of non-sulfonated cyanines have low aqueous solubility except for hydrochlorides of hydrazides and amines. For biomolecule labeling, the labeling reagent has low aqueous solubility, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer.
The ENU cells immersed in 0.3 mM Cy3.5 NHS ester with modified balanced salt solution (MBSS) showed that Cy3.5 NHS ester does not label the dead cells [1].
