Product Description

BactoView™ Live dyes are fluorogenic live cell bacterial DNA stains. Bright and cell-permeant, they are able to stain both live and dead gram-positive and gram-negative bacteria for microscopy or flow cytometry.

  • DNA dyes for bacteria
  • Stain live and dead, gram-positive and gram-negative cells
  • Choose green or red fluorescence
  • Supplied at 500X in DMSO

BactoView™ Live dyes can stain both live and dead bacteria; dead cells tend to stain more brightly 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.

Biotium also offers BactoView™ Dead Stains and BactoView™ Viability Kits for highly-selective staining of dead bacteria, available in a selection of 7 colors from green to near-IR. BactoView™ Dead Stains also can be combined with fluorescent Gram stains like our CF® Dye WGA Conjugates. For bright and optimized labeling of bacterial endospores, see our BactoSpore™ Bacterial Stains.
