General description

Sulforhodamine 101 is a red fluorescent dye. It is water-soluble, amphoteric rhodamine.

Application

Sulforhodamine 101 has been used:
  • to label astrocytes
  • in quantitative polymerase chain reaction (PCR)
  • to determine the degree of disintegration in tissue sample

Biochem/physiol Actions

Sulforhodamine 101 can be specifically used as a marker of astroglia in the neocortex. It is commonly used for brain imaging. Studies suggest that sulforhodamine 101 may be used as an epileptogenic agent.
