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.
描述了包含aza-苯并唑环部分的非对称花青染料,包括通过阳离子侧链取代的花青染料、单体和多聚花青染料、化学活性花青染料以及花青染料偶联物。主题染料在水溶液中稀释时几乎无荧光,但当与核酸聚合物如DNA或RNA结合,或与洗涤剂-蛋白质复合物结合时,则表现出明亮的荧光。描述了用于检测和定量各种样品中的核酸和洗涤剂-蛋白质复合物的一组应用,包括溶液、电泳凝胶、细胞和微生物。
