Cyanine3B dye azide for сlick сhemistry conjugation with terminal alkynes via a copper-catalyzed click reaction or strained cyclooctynes via a copper-free click reaction.
Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability. Due to the fixed conformation, Cyanine3B has the highest emission quantum yield compared to other dyes of this wavelength.
This is a sulfonated dye and can be used for efficient labeling in water media.
Lumiprobe推出了生命科學研究中最受歡迎的花青染料Cyanine。這些染料是自 1970 年代以來用於血管造影的花青染料吲哚菁綠 (ICG) 的改進型,並發現這些染料與生物分子的非特異性結合較低,且由於其巨大的消光係數和良好的量子產率而具有明亮的螢光。這些分子在 CMU 專利到期後,現正以親善的價格廣泛地進入生命科學應用等領域。花青染料Cyanine可用於標記許多類別的目標,包括:可溶性蛋白質、抗體、DNA 和寡核苷酸、Peptides、許多小分子。
