摘要： A method is provided for detecting up to four classes of oligonucleotides which have been separated by gel electrophoresis. The method entails labeling members of each class of oligonucleotide with dyes selected from separate sets of dyes so that members of the same class are labeled with dyes from the same set. The four sets of dyes of the invention consist of derivatives of fluorescein, 2',7'-dimethoxy-4', 5'-dichlorofluorescein, tetramethylrhodamine, and rhodamine X carboxylic or sulfonic acid, respectively. Dyes from these sets are spectrally resolvable under conditions of gel electrophoresis.

摘要： The present invention provides novel immunolabeling complexes and certain components of such complexes, as well as methods of preparing and using such complexes, and kits for use in preparing labeling proteins and for immunolabeling. The pre-formed immunolabeling complexes of the invention comprise both a target-binding antibody and a labeling protein that contains covalently attached labels, where the labeling protein binds selectively and with high affinity to a selected region of the target-binding antibody. Novel labeling proteins of the invention include non-antibody peptides and proteins, such as a complex of protein G and a labeled albumin, and monovalent antibody fragments, such as labeled Fab fragments of an anti-Fc antibody. In methods of the invention, the preformed immunolabeling complexes are added to the sample alone or in combination, for purposes of labeling and optionally detecting the target of interest.

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.

摘要： The invention describes reactive dyes having an alkyl spacer attached via a sulfonamide bond to a sulforhodamine 101 fluorophore, and a variety of useful conjugates prepared therefrom. The increased length of the covalent linkage due to the alkyl spacer results in dye-conjugates having a number of surprisingly advantageous properties relative to previous sulforhodamine 101-labeled conjugates, including enhanced solubility and increased fluorescence. The reactive dyes of the present invention are more stable than the known compound sulforhodamine 101 sulfonyl chloride. Novel reactive dyes are described for selective modification of groups other than amines, including thiols and photoreactive derivatives.

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.
