Cyanine7 azide is a near-infrared fluorescent dye azide for click chemistry labeling, an analog of Cy7® azide.

This product can be used for the incorporation of Cyanine7 into various alkynylated biomolecules via click chemistry. Post-synthetic modification of oligonucleotides is also possible with this azide.

Cyclohexane-bridged polymethyne chain allows for 20% increase in quantum yield (compared to parent non-bridged structure).

 

Lumiprobe 全新推出生命科學研究中最受歡迎的花青染料 —— Cyanine 系列。這些染料為 1970 年代廣泛應用於血管造影的經典花青染料吲哚菁綠(ICG)之改良版,具備更低的非特異性生物分子結合特性,並因其高消光係數及優異量子產率,展現出明亮且穩定的螢光表現。隨著 CMU 專利到期,這些高效能分子現已以更親民的價格,廣泛應用於各類生命科學領域。Cyanine 染料可用於標記多種目標,包括可溶性蛋白質、抗體、DNA 與寡核苷酸、胜肽(Peptides)及各類小分子。
