The laboratory determination of serum and urine amylase activity is commonly requested by the Emergency physician. While depressed levels are occasionally seen, they are almost always secondary to chronic pancreatitis and pancreatic destruction.

A micromodification of Somogyi’s starch-iodine colour method for determination of α-amylase in media from salivary gland tissue cultures, as well as homogenates of such tissues and in saliva, is described. The method was based on photometric determination of the starch-iodine colour changes during enzymic degradation of starch substrate at wavelengths ...

The amylases are a group of enzymes responsible for the breakdown of starches into sugars. The important amylase in animals is α-amylase (EC3.2.1.1 – alternate names 1,4-α-D-glucan glucanohydrolase, or glycogenase) which is a calcium metalloenzyme that acts at random locations along a starch molecule hydrolyzing α-1,4 links to ultimately yield mono ...

Excessive amounts of amylase were determined in 22 normal human tonsils by Winslow's method for the determination of serum amylase. The amylase content ranged from 44 to 704 U, mean 161 U. Since some malignant neoplasms are known to produce amylase, the present estimations might serve as a baseline for further investigation of lymphomas and carcinomas ...

Abstract 1. 1. Robinia pseudo-acacia honey and Apis mellifera food gland amylase display optimal activity at pH 5·6–5·9 and 45°C, with a persistent feeble activity at 80°C. The chloride ions (0·1 M) are the activators of both enzymes. 2. 2. R.

Amylase zymography was carried out for the detection of amylases produced by a Geobacillus stearothermophilus strain isolated from the Thermal Center "Las Trincheras" in Venezuela. Zymography is an electrophoretic technique used to study hydrolases by means of thin gels containing copolymerized-specific substrates, under nonreducing conditions. In this

Chromatographic methods for amylases
Journal of Chromatography B: Biomedical Sciences and Applications, 1996This review surveys recent developments in chromatographic methods for the separation of amylases from complex extracts, including the separation of isozymes. It contains two tables with the properties and molecular characteristics of alpha-and beta-amylases from different sources as well as an updated review of methods for the determination of amylase

Encapsulation of Amylase in Colloidosomes
Langmuir, 2014Aqueous core colloidosomes encapsulating the enzyme amylase were manufactured with a shell comprising polymer latex particles of diameter 153 nm. The colloidosomes were sealed with calcium carbonate by precipitation between an inner phase of Na2CO3 and an outer phase of CaCl2. This seal allowed the retention of small molecules, such as dyes, as well as

IT has previously been observed that crystalline salivary amylase gives two peaks in free electrophoresis1. The work recorded here shows that a sample of salivary amylase crystallized three times, which gave a single peak in the ultracentrifuge (Fig. 1), could be separated into four bands by disk electrophoresis on polyacrylamide gel2 (Fig. 2).
