Unsymmetrical cyanine dyes that incorporate an aza-benzazolium ring moiety are described, including cyanine dyes substituted by a cationic side chain, monomeric and dimeric cyanine dyes, chemically reactive cyanine dyes, and conjugates of cyanine dyes. The subject dyes are virtually non-fluorescent when diluted in aqueous solution, but exhibit bright fluorescence when associated with nucleic acid polymers such as DNA or RNA, or when associated with detergent-complexed proteins. A variety of applications are described for detection and quantitation of nucleic acids and detergent-complexed proteins in a variety of samples, including solutions, electrophoretic gels, cells, and microorganisms.
本文描述了包含氮杂苯并咪唑环基团的非对称青光菁染料,包括带有阳离子侧链的青光菁染料、单体和二聚体青光菁染料、化学反应性青光菁染料和青光菁染料的共轭物。当在水溶液中稀释时,这些染料几乎不发荧光,但当与核酸聚合物如DNA或RNA结合或与复合物化的蛋白质结合时,表现出明亮的荧光。本文还描述了在各种样品中检测和定量核酸和复合物化蛋白质的各种应用,包括溶液、电泳凝胶、细胞和微生物。
