โฆ Synopsis
Proline, 4-hydroxyproline, and 3-hydroxyproline are combined with 7-chloro-4-nitrobenzo-2-oxa-I ,3-diazole and the fluorescent derivatives separated by thin-layer chromatography on silica gel prior to spectrofluorometric determination. The method is sensitive to 1 pmol, reproducible, and fast. It also permits the measurement of the specific activities of proline and the hydroxyprolines.
' Abbreviation used: NBD-chloride, 7-chloro-4-nitrobenzo-2-oxa-l,3-diazole.
