Preparation of enzyme calibration materials

Clinica Chimica Acta, 1998
Standardisation in clinical enzymology needs not only reference methods but also reference materials. While single-enzyme reference enzymes have been developed, a multienzyme certified reference material (MECRM) available in high amount remains to be produced.

Enzymic Activities of Commercial Preparations of Pancreatic Enzymes

Scottish Medical Journal, 1977
The enzymic activities of 20 commercial pancreatic extracts have been measured by standard (F.I.P.) methods of assay and the activities have been compared with a standard preparation of pancreatin supplied by the British Pharmacopoeia Commission. A wide range of enzymic activities was found. The tabulated cost per unit of enzymic activities provides a

Use of genetically prepared enzyme conjugates in enzyme immunoassay

Trends in Biochemical Sciences, 1993
Enzyme immunoassay, using enzymes crosslinked to either antibodies or antigens, has proved a valuable immunological tool for many years. Recently, gene fusion techniques have been used to prepare these enzyme conjugates. This method may be especially advantageous in cases where (1) the antigen is difficult and costly to obtain in large quantities or (2)

The Enzymic Preparation of Diphosphoinositides

Preparative Biochemistry, 1977
A procedure for the preparation of diphosphoinositides is described. Triphosphoinositides isolated from bovine brain are hydrolysed by the triphosphoinositide phosphatase (EC 3.1.3.36) from Crithidia fasciculata in the presence of MgC12 and cetyltrimethyl-ammonium bromide.

Enteric spherules diastase in enzyme preparations

Journal of Microencapsulation, 1991
Enteric diastase spherules were prepared using cellulose acetate phthalate and eudragit RS-100 by emulsion solvent removal method. Factors that could affect the size shape and diastatic activity were studied. The studied factors include pH of aqueous media, temperature of dispersion media and concentration of surface active agent.

Recent preparative applications of redox enzymes

Current Opinion in Chemical Biology, 2019
Redox enzymes offer many powerful transformations for the efficient industrial-scale synthesis of diverse chemicals desired by society. Here we survey recent preparative applications of redox enzymes, highlighting both mature enzyme platforms and promising technologies for future applications.
