General description

Neutral red (C.l. 50040, Cl Basic red 5) is a protonated diaminophenazine dye that has a small planar conjugated system.

Application

Neutral red has been used in several histological staining applications that include:
  • as a nuclear stain
  • as a counterstain in the Gram procedure, either alone, or as a component of the Twort stain, a fast green-neutral red mixture.
  • fluorescent staining of nucleic acids in nervous tissue, of lipids and hydrophobic substances such as suberin and of phenolic compounds in algal cell walls
  • detection of viable yeast cells in dandruff samples and of mussel larvae
  • Neutral red has also been used as a stain in flow cytometry.
Useful as an indicator for preparing neutral red paper, and as a biological stain.

Mitochondrial dysfunction plays an important role in kidney damage in various pathologies, including acute and chronic kidney injury and diabetic nephropathy. In addition to the well-studied ischaemia/reperfusion (I/R) injury, hypothermia/rewarming (H/R) also inflicts acute kidney injury. Substituted 6-hydroxychromanols are a
