Application

Quinaldine Red has been used as a fluorescent probe for α1-acid glycoprotein (AAG).

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.

We examined different fluorescent probes suitable for fluorometric determination of alpha 1-acid glycoprotein (AGP) in serum. Quinaldine red (QR) was shown to bind strongly and selectively to AGP. Taking advantage of the enhanced fluorescence of QR in the presence of

We attempted to develop a fluorescent probe superior to conventional ones (8-anilino-1-naphthalenesulfonate and auramine O) for use in the study of drug-binding sites on alpha 1-acid glycoprotein (AGP). It was found that quinaldine red (QR) strongly bound to AGP and

The acute-phase response alters the composition of carrier proteins in plasma, which may affect the blood deposition and transport of biomediators and drugs. The effect of the acute-phase response on the ligand binding ability of plasma was studied in leukemic

Miniaturization of high-throughput screening (HTS) assays has several obvious advantages, including increased throughput and lower cost by reduction in reagent consumption. Although absorbance assays are widely used in research laboratories, their application for HTS in a low-volume format has been
