摘要:
Bis-diazo, triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides and polypeptides. The quencher moieties are non-fluorescent and accept energy transfer from fluorescent reporter labels by any energy-transfer mechanism, such as FRET.Fluorescence quencher compositions are useful in preparing quencher labeled biomolecules for various molecular biology assays based on fluorescence detection.

摘要:
Highly efficient cationic liposomes are provided as a system for the delivery to cells of agents or compounds, such as, compounds capable of silencing a target protein and enzyme substrates. The cationic liposomes can be used in methods of detecting the inhibition activity or apparent activity of a target protein in a cell, and methods of identifying a protein associated with a pathway, such as, a signal transduction pathway in a cell.

摘要:
The present invention provides novel, water-soluble, red-emitting fluorescent rhodamine dyes and red-emitting fluorescent energy-transfer dye pairs, as well as labeled conjugates comprising the same and methods for their use. The dyes, energy-transfer dye pairs and labeled conjugates are useful in a variety of aqueous-based applications, particularly in assays involving staining of cells, protein binding, and/or analysis of nucleic acids, such as hybridization assays and nucleic acid sequencing.
