SUBSTITUTED UNSYMMETRICAL CYANINE DYES WITH SELECTED PERMEABILITY

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. The cyanine dyes of the invention possess a high sensitivity to oligonucleotides and larger nucleic acid polymers in a wide range of cells and gels, and are useful for the analysis of cell structure, membrane integrity or function, and determination of cell cycle distribution. 00000
