Sulforhodamine B or Kiton Red (C27H30N2O7S2; Molecular Weight 558.66 grams/mole) is a fluorescent dye with uses spanning from L.I.F.(Laser Induced Fluorescense) to the quantification of cellular proteins of cultured cells. The red, solid, water soluble dye is primarily used as a polar tracer.

The dye absorbs 565nm light and emits 586nm light. It does not exhibit pH dependent absorption or fluorescence over the range of 3 to 10 [cite journal | author= Coppeta, Rogers | title= Dual Emission Laser Induced Fluorescence for Direct Planar Scalar Behavior Measurements | journal=Experiments in Fluids | year=1998 | volume= 25| issue= | pages=1–15; | url= | doi= 10.1007/s003480050202] .
