产品简介

Cy3 Tetrazine|Cyanine3 tetrazine
TAMRA 荧光染料是在用的多种不同共轭物中Z受欢迎的荧光试剂之一,可标记蛋白质和寡核苷酸。TAMRA具有吸光的性质,它的光谱与几类常用的荧光化合物重叠,TMR是明亮的橙色荧光基团。

详细介绍

Cy3 Tetrazine|Cyanine3 tetrazine

 

Tetrazines demonstrate exceptionally fast cycloaddition kinetics (up to 30 000 M-1 s-1) with trans-cyclooctenes (TCO) as the dienophile, the fastest kinetics ever reported for any bioorthogonal reaction. In addition, inverse-Electron-Demand Diels-Alder reaction of tetrazines trans-cyclooctenea forms a stable covalent bond and does not reuire Cu-catalyst or elevated temperatures. In applications such as in vivo cancer imaging or pre‐targeted cell labeling studies where rapid reaction kinetics are desired, a faster hydrogen substituted Cy®3 Tetrazine probe would be a probe of choice.
 
Cy®3 is a bright, water-soluble, and pH insensitive orange-fluorescent dye that can be excited using the 532 nm or 555 nm laser line and visualized with TRITC (tetramethylrhodamine) filter sets. Cy3 conjugates give less background than TAMRA and most other monly used fluorescent dyes.
