Local detection of enzymatic ion generation with polycrystalline silicon interdigitated electrodes and its application to biosensing [PDF]
Chips containing polycrystalline silicon interdigitated electrodes are modified with the enzyme urease. The sensors are able to detect changes in the resitivity of the solution near their surface, where the enzymatic reaction generates charged species ...

Total tissue lactate dehydrogenase activity in endometrial carcinoma [PDF]
Lactate dehydrogenase (LDH) is essential for continuous glycolysis necessary for accelerated tumor growth. The aim of this study was to reconsider if assay of total tissue activity of this enzyme could be useful as marker for endometrial carcinoma (EC ...

Deactivation of TEM-1 beta-Lactamase investigated by isothermal batch and non-isothermal continuous enzyme membrane reactor methods [PDF]
The thermal deactivation of TEM-1 β-lactamase was examined using two experimental techniques: a series of isothermal batch assays and a single, continuous, non-isothermal assay in an enzyme membrane reactor (EMR).

The Development of Assays for Heparanase Enzymatic Activity: Towards a Gold Standard
The enzyme heparanase, an endo-β-glucuronidase, degrades heparan sulfate (HS) chains on the cell surface and in the extracellular matrix. Heparanase regulates numerous biological processes that drive tumour growth, metastasis and angiogenesis.

Lipase activity in vesicular systems: Characterization of candida cylindracea lipase and its activity in polymerizable dialkylammonium surfactant vesicles [PDF]
Lipase from Candida cylindracea (CCL) was incorporated into polymerizable positively charged dialkylammonium bromide surfactant vesicles. The enzyme was incorporated by the use of the dehydration-rehydration method or by incubation.
