Polarisation fluoroimmunoassay for quinine in serum and urine.

The development and validation of a polarisation fluoroimmunoassay for the antimalarial drug quinine is described. The assay is performed either by sequential addition of the reagents or by a single-reagent technique whereby the tracer and antibodies are premixed. Serum samples require pepsin digestion prior to assay while urine specimens are assayed… (More)
