产品介绍

Cy5 叠氮化物是美国AAT Bioquest生产的Cy系列染料，各种花青5（Cy5）染料已用于标记生物分子，用于荧光成像和其他基于荧光的生化分析。它们用于标记肽，蛋白质和寡核苷酸等。Cy5 染料是常见的红色荧光团中的一种。这些多功能荧光团可以耐受3-10的pH范围，用于生物相关pH的各种应用。该染料还具有DMSO耐受性和光稳定性，能够在不损失性能的情况下从储存转移至分析。水溶性在测定缓冲液中对有机溶剂的需要。我们的Cy5染料经过QC测试，可确保高水平的发色团和活性染料含量。单活性染料适用于蛋白质和寡核苷酸的靶向，标记，双活性染料更适合于一般标记。建议使用NHS酯染料标记胺基，建议使用马来酰亚胺染料标记硫醇基团。该Cy5 叠氮化物选择性地与炔基反应。百萤生物是AAT Bioquest的代理商，为您提供优质的Cy5 叠氮化物。

A variety of cyanine 5 ( Cy5?) 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.  Cy5? 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. Our Cy5? Fluors are thoroughly QC tested to ensure high levels of chromophore and reactive dye content. Mono-reactive dyes are suitable for targeted, precise labeling of proteins and oligonucleotides and bis-reactive dyes are more suitable for general labeling. NHS ester dyes are recommended for labeling amine groups and maleimide dyes are recommended for labeling thiol groups. This Cy5? azide selectively reacts with alkyne groups.
