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.
描述了一种包含氮杂苯并咪唑环基团的不对称靛烷染料,包括带有阳离子侧链的靛烷染料,单体和二聚靛烷染料,化学反应性靛烷染料以及靛烷染料的共轭物。这些染料在水溶液中稀释时几乎不发荧光,但与核酸聚合物(如DNA或RNA)或与复合物化的蛋白质相结合时,会表现出明亮的荧光。描述了用于检测和定量各种样品中的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。
