A sensitive agarose diffusion method for the determination of cY-amylase has been developed, using Reactone Red 2 B-amylopectin as the substrate. The logarithm of enzyme activity is linearly correlated with the diameters of the diffusion zones over a very extended range from 1 mu/ml to at least 1100

The specific radioactivity of a choline phospholipid has been determined by a double-isotope method. Purified phospholipid was hydrolyzed to release labeled choline, and choline kinase was employed to label the choline with 32P from [-Y-~\*P]ATP. The double-labeled phosphorylcholine was purified by
A direct and sensitive liquid chromatographic method for the determination of propofol in 50 microliters of plasma is described. The separation of the drug and internal standard (methyldopa) was achieved using a 4 microns particle size C1R cartridge (10 cm x 8 mm i.d.) in conjunction with a radial c
