Sulfo-Cyanine3 NHS Ester說明：

A variety of cyanine dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc. Cy3® dyes are one type of the most common red fluorophores. These versatile fluorophores can tolerate a pH range of 3-10 for use in a variety of applications at biologically relevant pHs. The dyes are also DMSO tolerant and photostable to enable transfer from storage to assay without loss of performance. The aqueous solubility eliminates the need for organic solvents in the assay buffers. Sulfo-Cyanine 3 is an alternative dye primarily used for labeling peptides and oligos in replacing Cy3 that was originally developed by GE Healthcare (Cy3® is the trademark of GE Healthcare). NHS ester dyes are recommended for labeling amine groups and maleimide dyes are recommended for labeling thiol groups. This Cy3® NHS ester readily reacts with amino groups.

Sulfo-Cyanine3 NHS Ester 實驗注意事項：
1.實驗前需戴好防護(hù)眼鏡，穿戴防護(hù)服和口罩，佩戴手套，避免與皮膚接觸。
2.實驗過程中如遇到有毒或者刺激性物質(zhì)及有害物質(zhì)產(chǎn)生，必要時實驗操作需要手套箱內(nèi)完成以免對實驗人員造成傷害
3.實驗后產(chǎn)生的廢棄物需分類存儲，并交于專業(yè)生物廢氣物處理公司處理，以免造成環(huán)境污染Experimental considerations:
1. Wear protective glasses, protective clothing and masks, gloves, and avoid contact with the skin during the experiment.
2. The waste generated after the experiment needs to be stored separately, and handed over to a professional biological waste gas treatment company to avoid environmental pollution.
