Description générale

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.

Actions biochimiques/physiologiques

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.

We report on a novel laser-induced fluorescence triple-integration method (LIFTIME) that is capable of making rapid, continuous fluorescence lifetime measurements by a unique photon-counting technique. The LIFTIME has been convolved with picosecond time-resolved laser-induced fluorescence, which employs a high-repetition-rate mode-locked
