Measurement of amylase activity.
The Nelson photoelectric method for the determination of glucose in biological fluids (1) has proved to be the method of choice in this laboratory and in many others, owing to its reproducibility, stability of color, and excellent agreement with the Beer-Lambert law. Nelson, however, states that the method is unsuitable for the determination of diastatic activity. Since it is convenient and eco...

متن کاملRecent advances in measurement of amylase activity--a comparative study.
We evaluated four kinetic amylase procedures with respect to kinetics, analytical range, blank rates, reagent stability, reagent impurities, interfering substances, and intrinsic sensitivities. Each of the methods is shown to have its own unique advantages and disadvantages. A preliminary discussion of some alternative methods, in which glycosidic p-nitrophenyl alpha-oligosaccharides are substr...
متن کاملKinetic nephelometric procedure for measurement of amylase activity in serum.
We developed a kinetic procedure for determination of amylase activity in serum by use of nephelometric measurements. Light scattering from the substrate, a stable suspension of starch, is decreased as amylase hydrolyzes the starch to soluble fragments. Values obtained for serum amylase correlate closely with those determined by a method in which a starch-dye complex is used. Precision of the n...
متن کاملMeasurement of renin activity in human plasma.
• Many methods for measurement of renin activity have been described since Tigerstedt and Bergman first made an extract of kidney and showed that when injected it raised blood pressure. Those methods which rely on the rise of blood pressure following such injections suffer from three main disadvantages. First, the magnitude of response to a given dose may vary and tachyphylaxis can be elicited....
