Efficient preservation in a silicon oxide matrix of Escherichia coli, producer of recombinant proteins

The aim of this work was to study the use of silicon oxide matrices for the immobilization and preservation of recombinant-protein-producing bacteria. We immobilized Escherichia coli BL21 transformants containing different expression plasmids. One …

Plasmatic antioxidant capacity due to ascorbate using TEMPO scavenging and electron spin resonance

Background: Ascorbate is the most effective water-soluble antioxidant and its plasma concentration is usually measured by different methods including colorimetric assays, HPLC or capillary electrophoresis. Plasma antioxidant capacity is determined by …
