SYTOX® Dead Cell Stains




Invitrogen offers Molecular Probes® cell-impermeant nucleic acid  SYTOX® Dead Cell Stains.  Because they do not cross intact cell membranes  and also increase fluorescence upon dsDNA binding they are among our most brilliant dead cell stains.  Easy to use, SYTOX® dead cell stains can be applied to cells and visualized without an additional wash step because they are non-fluorescent in aqueous media. These stains can be used on multiple platforms including fluorescence microscopy, flow cytometry, and microplates.

SYTOX® Green Dead Cell Stain

SYTOX® Green dead cell stain has the highest nucleic acid affinity of all of the SYTOX® dead cell stains. Exhibiting a 100-fold increase in fluores- cence upon nucleic acid binding and minimal base selectivity (unlike DAPI and propidium iodide), SYTOX® Green dead cell stain is great for multi-parametric analysis with blue- or red- fluorescent labels.

SYTOX® Orange Dead Cell Stain

SYTOX® Orange dead cell stain binds nucleic acids in cells with compromised membranes. This stain is useful as an indicator of cell death and is much brighter than propidium iodide.

SYTOX® Red Dead Cell Stain

SYTOX® Red dead cell stain is a simple and quantitative single-step dead-cell indicator for use with red laser-equipped flow cytometers. SYTOX® Red dead cell stain is a high-affinity nucleic acid stain that easily penetrates cells with com- promised plasma membranes but will not cross uncompromised cell membranes.

SYTOX® Blue Dead Cell Stain

SYTOX® Blue dead cell stain is a simple and quantitative single-step dead-cell indicator for use with violet laser equipped flow cytometers. SYTOX® Blue dead cell stain is a high-affinity nucleic acid stain that easily penetrates cells with compromised plasma membranes but will not cross uncompromised cell membranes.
