General description

Quinine hemisulfate salt monohydrate is a naturally occurring well known fluorescent standard material. Quinine hemisulfate salt monohydrate or QSM has a fluorescence lifetime between 1.0 to 3.0 ns.

Application

Quinine hemisulfate salt monohydrate is used for indirect photometric detection of polyamines in biological samples. It is suitable for studying metabolism of bio crystalized heme, hemozoin, in malarial parasites and to study the toxicity of heme (FP)-complexes.

Biochem/physiol Actions

Potassium channel blocker. Antimalarial, anticholinergic, antihypertensive, and hypoglycemic agent; alkaloid originally isolated from the Cinchona family of South American trees. Inhibits mitochondrial ATP-regulated potassium channel. Used to study the metabolism of biocrystalized heme, hemozoin, in malarial parasites and to study the toxicity of heme (FP)-complexes.
