neutral red

Neutral red is added to some growth media for bacterial and cell cultures.

Neutral red can be used as a vital stain.

As cells begin to die, their ability to incorporate neutral red diminishes.

Different formulations use different indicators; neutral red is often used.

It is known commercially as neutral red.

Live cells incorporate neutral red into their lysosomes.

Colonies of B. pseudomallei also take up neutral red which is present in the medium, and this further helps to distinguish it from other bacteria.

Neutral red (or toluylene red) stains Nissl substance red.

Another cell viability endpoint can be Neutral Red (NR) uptake.

Although some authors refer to NLFs as being colourless, in reality they turn neutral red a buffish color.

Falsely using the neutral Red Cross emblem is against the Geneva Conventions as it could put humanitarian workers at risk in war zones.

Nuclei - red with Neutral Red/Safranin staining.

Haematocrit, phagocytosis, Neutral Red retention time, and lysozyme and superoxide dismutase activities were evaluated.

Neutral red accumulates in membraned structures associated with the peripheral cytoplasm that correspond to secondary vacuoles in morphology and movement.

They were then counter-stained in 1% neutral red, dehydrated in an ethanol series, cleared in xylene, and mounted in permount.

Neutral Red, a weak cationic dye penetrates cellular membranes by non-diffusion and accumulates intercelluarly in lysosomes.

Enteric bacteria that have the ability to ferment lactose can be detected using the carbohydrate lactose, and the pH indicator neutral red.

These cells resemble dorsal unpaired median neurons in that they possess similar morphological and neurophysiological properties, show an affinity for neutral red, and contain octopamine.

The neutral Red Cross - whose reports are confidential unlike those of U.N. investigators - still seeks a wider agreement for access to all prisoners held by Iraq.

Intracellular pH can be measured quantitatively in rat brain in vivo and in vitro using spectrophotometric detection of the vital dye neutral red.

The electron transfer from microbial cells to the electrode is facilitated by mediators such as thionine, methyl viologen, methyl blue, humic acid, and neutral red.

Lactose and neutral red are added to differentiate the lactose fermenters, which form pink colonies, from lactose nonfermenters that form clear colonies.

A 2nd order polynomial relationship between absorption and concentration is sometimes encountered for very large, complex molecules such as organic dyes (Xylenol Orange or Neutral Red, for example).

Biological analyses included cytotoxicity assessment via the Neutral Red Uptake Assay, and mutagenicity testing via the Salmonella Mutagenicity Assay.
