A new, rapid and sensitive assay of ADPglucose pyrophosphorylase using the luciferaseluciferin system to quantify the reaction product, ATP, is described. The total assay time per sample is about 10 min. The sensitivity ranges from picomoles to nanomoles, and the crude enzyme extract from individual

โฆ Synopsis
A procedure has been developed for the separation of labeled fatty acids from tri-, di-, and monoglycerides using small disposable columns of TEAE-cellulose.
This procedure is used as the basis of a lipase assay which is rapid, sensitive and unaffected by wide variations in the composition of the reaction mixtures. 0.5 nmole ['4C101eic acid can be debected, and the entire procedure requires less than 3 min.

A gas-liquid chromatographic (glc) assay for abscisic acid (ABA) is described that is both rapid and highly sensitive. The selectivity and sensitivity of an electroncapture detector are used to reduce the assay procedure to just four steps: extraction, thin-layer chromatography (tic), esterification
