General description

Sulforhodamine B is a rhodamine derived aminoxanthene dye. It contains two sulfonic acids groups which separate in alkaline condition.

Application

Sulforhodamine B sodium salt has been used:
  • for relative total cell mass quantification
  • to investigate the viscosity of coacervates
  • as a molecular rotor for microviscosity determination in aerosol droplets

Biochem/physiol Actions

Sulforhodamine B sodium salt is useful to measure cell biomass and also for cytotoxicity screening.
