Improved high-performance liquid chromatographic determination of biotinidase activity with biotinyl-6-aminoquinoline as substrate.


An improved high-performance liquid chromatographic assay method for biotinidase activity was developed using the fluorimetric substrate biotinyl-6-aminoquinoline, which was found to be more specific than the biotinyl-4-aminobenzoate previously used. The new method measures the intensity of the fluorescent signal at wavelengths (excitation 350 nm; emission… (More)
