Bacterial Viability

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

This kit provides two-color fluorescence staining of both live bacteria (green) and dead bacteria (red) using two DNA dyes, DMAO and EthD-III.

Highly-selective dead cell stains for bacteria cultures. The stains are suitable for both gram-positive and gram-negative strains.

These kits include a BactoView™ Dead Stain and BactoView™ Viability Green Counterstain for two-color staining of live and dead bacteria. The kit is suitable for both gram-positive and gram-negative strains.

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.

5-Cyano-2,3-ditolyl tetrazolium chloride (CTC) has been used to evaluate the respiratory activity of many bacterial populations as well as populations undergoing drug efficacy evaluations.  Healthy cells respiring via the electron transport chain will absorb and reduce CTC into an insoluble, red fluorescent formazan product.
