Indirect Detection of Glycosidases Using Amperometry

BharatP. Gurale (2067166), Abasaheb N. Dhawane (2581501), Xikai Cui (2581498) et al. · Figshare · 2016

Glycosidases are essential enzymes\nthat cleave glycoside bonds.\nThe presence of glycosidases have been widely used to detect pathogens,\nlabel cells/tissues, and report specific diseases. We have developed\na rapid electrochemical assay to detect glycosidases. Exposure of\nelectrochemically inactive substrates to glycosidases releases glucose,\nwhich can be measured easily using an electrochemical cell. Five different\nglycosidases were detected rapidly within 1 h using disposable electrodes.\nThis assay could readily be incorporated into repurposed glucose meters\nto rapidly detect glycosidases, which in turn could be useful to report\nthe presence of a pathogen or illness.

Good Practices in Single-Cell Amperometry

José David Machado, Mónica S. Montesinos, Ricardo Borges · Methods in molecular biology · 2008

Single-cell amperometry is a powerful tool for the study of the mechanisms underlying secretion from cells that release electrochemically active substances like catecholamines, histamine, or serotonin. Amperometry has changed our view of the secretory process and the quantal release phenomenon. Today, it is a relatively easy technique to set up and affordable for most laboratories. Amperometry can help solve many interesting problems in cell physiology or pharmacology. However, there are a number of issues about the experimental design, data analysis, and result interpretation that need to be considered. Here, we compile some recommendations and advice on how to conduct experiments with amperometry, covering tissue culture, electrode types and their construction, calibration, equipment, data acquisition, and strategies for electrical noise reduction. We concentrate on cultured chromaffin cells, although most of the information is equally applicable to other cell types.

Determination of creatinine using pulsed amperometry

Dominika Giampaglia · Digital Repository (National Repository of Grey Literature) · 2021

This diploma thesis deals with the determination of creatinine using a combination of flow injection analysis (FIA) or high-performance liquid chromatography (HPLC) with pulse amperometry, an electrochemical technique based on the application of potential pulses on a gold working electrode. The determination was performed in a basic environment of borate buffer with creatinine concentration of 1∙10-4 mol∙l-1 . The lenght of the cleaning and activation pulse was optimized as well as the pH of the running buffer. A cleaning pulse of +1.8 V was first applied to the electrode for 100 ms, then an activation potential of -0.5 V was applied for 150 ms and then a measuring potential of +0.2 V for 300 ms. The optimal pH was selected as pH=9,4. Methanol and acetonitrile were added to the borate buffer to test whether creatinine could be determined in presence of these organic solvents and whether flow injection analysis could be transformed into HPLC. Methanol in the system caused peak deformation, acetonitrile did not cause the peak deformation in the system, at higher contents the baseline was destabilized. Furthermore, the calibration dependence in the range of concentrations from 2.5∙10-4 mol∙l-1 to 5∙10-6 mol ∙ l-1 was measured using PAD in combination with FIA. At higher concentrations, peaks splitted....
