摘要： The invention describes the preparation and use of fluorescent stains for nucleic acids derived from unsymmetrical cyanine dyes comprising a substituted benzazolium ring system linked by a methine bridge to a pyridinium or quinolinium ring system having at least one substituent on the pyridinium or quinolinium ring that contains a heteroatom. The presence of the heteroatom-containing substituent results in higher sensitivity to oligonucleotides and larger nucleic acid polymers in a wide range of cells and gels, and for use in analysis of cell structure, membrane integrity or function.

摘要： The invention relates to a method of analyzing a sample thought to contain bacteria using an aqueous solution comprising one or more fluorescent dyes: a fluorescent dye of formula I, a fluorescent dye of formula II, a fluorescent dye of formula III, and a fluorescent dye of formula IV. Each of the dyes differ each from the other in their affinity for nucleic acids and in their spectral response to different types of bacteria in the sample. The first three dyes are nucleic acid stains and the fourth dye is a fluorescent reagent that binds selectively to cell surface components. The fluorescent dyes of formula I are highly membrane-permeant cyanine dye derivatives and label all bacteria, whether live or dead, whether Gram positive or Gram negative. The dyes of formula II label only live Gram positive bacteria and label all dead bacteria, whether Gram positive or negative. The dyes of formula II bind to nucleic acids preferentially with respect to the dyes of formula I. Fluorescent formula III dyes are membrane impermeant dyes that give a fluorescent signal only in cells with compromised plasma membrane integrity, whether Gram negative or Gram positive, and have a much higher binding affinity for nucleic acids than the fluorescent dyes of either formula I or formula II. Formula IV fluorescent dyes preferentially bind to an exterior component of a bacterium. The dyes are combined with a sample suspected of containing bacteria and illuminated at an appropriate wavelength to differentiate, according to the fluorescence response, live Gram negative, dead Gram negative, live Gram positive and dead Gram positive bacteria in the sample.

摘要： 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.

The dyes generally have the formula: ##STR1## where R.sup.1 is an alkyl group having 1-6 carbons; X is 0, S, or NR.sup.2, where R.sup.2 is an alkyl group having 1-6 carbons, or CR.sup.3 R.sup.4, where R.sup.3 and R.sup.4, which may be the same or different, are alkyl groups having 1-6 carbons;n=0, 1, or 2;Z.sup.1 and Z.sup.2, which may be the same or different, are independently hydrogen, an alkyl group having 1-6 carbons, or aryl, or Z.sup.1 and Z.sup.2 taken in combination complete a 6-membered aromatic ring;Y is HC.dbd.CH; andeach of P and M=0 or 2, such that P+M=1; andTAIL is an aminoalkyl chain containing a backbone of 3-42 carbons and 1-5 positively charged nitrogens intermittently or equally spaced within the backbone, such that there are at least two carbons between sequential nitrogens.

摘要： 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.
