Biochem/physiol Actions

Quinaldine Red (2-(p-Dimethylaminostyryl) quinoline ethiodide) is a very dark red or reddish-black colored powder. It has been used mainly for regulation of cell proliferation, in diagnostic agents of disease related with amyloid accumulation, detecting enzyme activity and dental bleaching materials. In addition, quinaldine red also been implicated in treatment of allodynia and virus infectious diseases. It is colorless at pH 1.4 and red at pH 3.2.[3][4]
