A red fluorescent dead cell stain for bacteria and mammalian cells

A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.

Ethidium bromide (EtBr) is a widely used nucleic acid gel stain although it is also a known potent mutagen. EtBr is an intercalating DNA-binding dye with little sequence preference.

Acridine orange (AO) stains dsDNA green (525 nm) and RNA or single stranded DNA red (650 nm). The dye is membrane-permeant and its nucleic acid binding property has been used for cell-cycle studies.

A high purity grade, red fluorescent nucleic acid dye for detecting nucleic acids in solution or for selectively staining dead cells with damaged plasma membranes.

A membrane-permeable DNA dye, excellent for staining both gram positive and gram negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry.

A fluorescent staining kit for live cell gram staining in bacteria. Suitable for fluorescence microscopy and flow cytometry.

A convenient assay for distinguishing between gram-negative and gram-positive, as well as live versus dead bacteria.

A photo-activated fluorescent nucleic acid binding dye used to selectively and covalently label dead cells in the presence of live cells for viability PCR, fluorescent microscopy, and flow cytometry.

Kits to covalently label dead cells, allowing cells with permeable plasma membranes to be excluded from analysis in flow cytometry. A wide variety of dye options for standard flow, spectral flow, and fluorescence microscopy.

A rapid and selective fluorescent assay to determine yeast viability in microscopy or flow cytometry applications. Contains two fluorescent components, CF® Dye-labeled Con A and Live-or-Dye™.
