Protein Profiling of Escherichia coli on exposure to imidacloprid

Explorer Protein abundance profiling of the Escherichia coli cytosol

Background: Knowledge about the abundance of molecular components is an important prerequisite for building quantitative predictive models of cellular behavior. Proteins are central components of these models, since they carry out most of the fundamental processes in the cell. Thus far, protein concentrations have been difficult to measure on a large scale, but proteomic technologies have now a...

Damage to Escherichia coli on exposure to moist heat.

The effects of temperatures of 50 to 60 C on suspensions of a strain of Escherichia coli are described. At these temperatures, the substances which leaked from the cells were determined as pentoses; the amount leaked over a 30-min period increased with increasing temperature. The leakage materials from suspensions heated in water, sodium chloride, sucrose, and sucrose plus Mg(++) were examined ...

Production of specific IgY antibody to the recombinant FanC protein produced in Escherichia coli

Objective(s): Enterotoxigenic Escherichia coli (ETEC) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. IgY technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. The purpose of this study was to produce specific antibody by egg yolk antibody (IgY...

Advances and challenges in recombinant protein expression in Escherichia coli

Transcriptome Profiling Reveals Interplay of Multifaceted Stress Response in Escherichia coli on Exposure to Glutathione and Ciprofloxacin

We have previously reported that supplementation of exogenous glutathione (GSH) promotes ciprofloxacin resistance in Escherichia coli by neutralizing antibiotic-induced oxidative stress and by enhancing the efflux of antibiotic. In the present study, we used a whole-genome microarray as a tool to analyze the system-level transcriptomic changes of E. coli on exposure to GSH and/or ciprofloxacin....
