1L-myo-Inositol-1-phosphatase, an enzyme purified from brain tissues, catalyzes the dephosphorylation of 1L-myo-inositol 1-phosphate. This enzyme has become the subject of intense research interest, since myo-inositol is needed for the resynthesis of phosphatidylinositol. We have developed a sensiti

โฆ Synopsis
A specific, sensitive bioluminescence assay for my&msitol is described employing myo-inositol dehydrogenase linked to a commercial NADH bioluminescence kit. Optimum conditions providing a linear response over 4 orders of magnitude are presented with reproducibility of 6% CV and a sensitivity of 1 pmol. The assay is suitable for the measurement of inositol at low concentrations or in Small VOhII'IeS.

Allantoin is separated by thin-layer chromatography (TLC) and sprayed with an acidic solution ofp-dimethylaminobenzaldehyde. The yellow color produced is read in a densitometer and compared with that of a standard. The lower limit of quantitation is 0.1 ~g per spot (0.5 mg/100 ml). The method can be
