Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability.
Cyanine3B carboxylic acid is a non-reactive form of Cyanine3B that can be used as a reference standard in experiments using conjugates of this fluorophore. Cyanine3B carboxylic acid can also be used to synthesize activated esters or modified with hydrazines, hydroxylamines, and amines for subsequent conjugation with biomolecules.
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。
