Product Description

BactoView™ Live dyes are fluorogenic live cell bacterial stains. Bright and cell-permeable, they are able to stain both gram-positive and gram-negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry. BactoView™ Live dyes can stain both live and dead bacteria, though dead cells tend to stain a bit brighter than live cells.

BactoView™ Live Green can stain mammalian cell nuclei, but BactoView™ Live Red shows weak mitochondrial signal in mammalian cells. In yeast, staining with either BactoView™ Live dye is weak and not nuclear. See our Cellular Stains Table for more information on how our dyes stain various organisms.

BactoView™ Live Red:

  • Red dye to stain live and dead bacteria
  • λExEm (with DNA) = 572/675 nm

BactoView™ Live Green:

  • Green dye to stain live and dead bacteria
  • λExEm (with DNA) = 500/520 nm
  • Detect in the FITC channel for flow cytometry and microscope


  • 500X in DMSO
  • Store at 4°C
