Online immunocapture ICP-MS for the determination of the metalloprotein ceruloplasmin in human serum
Globally, human exposure to environmental pollutants causes an estimated 9 million deaths per year and it could also be implicated in the etiology of diseases that do not appear have a genetic origin. Accordingly, there is need gain information about biomolecular mechanisms causally link inorganic with distinct adverse health effects. Although analysis blood plasma red cell (RBC) cytosol can pr...
This study investigated the larvicidal activity on Culex quinquefasciatus of lectin purified from fresh fruiting bodies woodland mushroom, Agaricus semotus. A. semotus (ASL) was via ion-exchange chromatography DEAE-cellulose A-25 and size exclusion Sephadex G-100 matrix. Molecular weight (16.6 kDa) estimated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The effects tem...
Iron-sulfur clusters are ubiquitous in biology and function in electron transfer and catalysis. They are assembled from iron and cysteine sulfur on protein scaffolds. Iron is typically stored as iron oxyhydroxide, ferrihydrite, encapsulated in 12 nm shells of ferritin, which buffers cellular iron availability. Here we have characterized IssA, a protein that stores iron and sulfur as thioferrate...
In the present study, we propose a method for bio-nano hybrid formation by coupling a redox metalloprotein, Azurin, with CdSe-ZnS quantum dot for the development of a nanoscale resistive memory device. The covalent interaction between the two nanomaterials enables a strong and effective binding to form an azurin/CdSe-ZnS hybrid, and also enabled better controllability to couple with electrodes ...
Electron-transfer kinetics of the thermophilic protein Plastocyanin from Phormidium laminosum adsorbed on 1,ω-alkanedithiol self-assembled monolayers (SAMs) deposited on gold have been investigated. The standard electron-transfer rate constant has been determined as a function of electrode-protein distance and solution viscosity over a broad temperature range (0-90 °C). For either thin or thick...
