The unactivated free carboxylic acid of near-infrared fluorescent dye Cyanine7. For coupling and labeling reactions also consider using pre-activated Cyanine7 NHS ester, or water-soluble sulfo-Cyanine7 NHS ester.
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。
