ATTO 647 is rhodamine-based fluorescent label for the red spectral region that has similar spectral properties to Cy5. It has strong absorption, high fluorescence quantum yield, high thermal and photostability, and its absorption and fluorescence are independent of pH from 2 to 11. ATTO 647 is suitable for single-molecule detection applications, high-resolution microscopy (such as SIM, STED), flow cytometry (FACS) and fluorescence in-situ hybridization (FISH).

Tetrazine reagents is a class of click chemistry labeling reagents containing a reactive tetrazine group, Tetrazine reagent is highly reactive with TCO (trans-cycloctene) in an inverse electron demand Diels Alder reaction followed by a retro-Diels Alder reaction to eliminate nitrogen gas. This is a very quick reaction for bioconjugation at low concentrations in labeling live cells, molecular imaging and other bioconjugation applications.

ATTO 647是一种基于罗丹明的荧光标记，用于红色光谱区，具有与Cy5类似的光谱特性。它具有强吸收、高荧光量子产率、高热稳定性和光稳定性，其吸收和荧光与pH值从2到11无关。ATTO 646适用于单分子检测应用、高分辨率显微镜（如SIM、STED），流式细胞术（FACS）和荧光原位杂交（FISH）。

四嗪试剂是一类含有活性四嗪基团的点击化学标记试剂，四嗪试剂与TCO（反式环辛烯）在反电子需求Diels-Alder反应中高度反应，然后进行反Diels-Alder反应以消除氮气。在标记活细胞、分子成像和其他生物结合应用中，这是一种低浓度生物结合的快速反应。
