Evidence that Pa ExoS-GAP activity can discriminate differences in Rho GTPases in tumor cells, beyond Rho or Rac activation, was provided by IF studies, which found MTC cells to contract but retain stably adhered branched actin filaments in response to Pa ExoS-GAP, which contrasted with the response of MTLn3 cells, where leading edge architecture was replaced with actin microspikes.
FISH analysis and semi-quantitative RT-PCR analysis indicated that all of these clones retained iHAC stably and independently from host chromosomes and consistently expressed four exogenous transgenes, constructed in the iHAC, as well as an EGFP gene.
Other open reading frames homologous to those of Shigella spp. in stx-flanking regions in E. coli have been described, and it is likely that E. coli and the shigellae have exchanged stx many times in their evolutionary past but only certain strains, such as 229/11, have the appropriate genomic background to retain and stably express Stx (9 ).
The multiple integrated cassettes were stably retained under prolonged nonselective conditions.
Furthermore, PNC-loaded catalase stably retained 25 30% of H2O2-degrading activity for at least 18 h in a proteolytic environment, while free catalase lost activity within 1 h.
The electrochemical tests demonstrate that the discharge capacity of the as-prepared polyaniline/anatase TiO2 microspheres can be stably retained at 157.1 mAh g−1 after 50th cycle at the high current density of 1500 mA g−1.
Given that pGL does not contain a known origin of replication for G. trabeum and that the transformed plasmids were stably retained in the absence of selective pressure, we infer that the transformed plasmids were integrated into the chromosomes of the transformants.
At the current density of 800 mA g−1, the discharge capacity can be stably retained at 861.6 mAh g−1 after 150 cycles for the composite prepared by adding ethanol, showing obvious advantages over the dry-milling sample and the composite prepared by adding chloroform.
A high discharge capacity of 812 mA h g−1 of sulphur (corresponding to 503 mA h g−1 of the whole cathode material mass) is stably retained after 200 cycles at 400 mA g−1 with a small average capacity decay of only 0.054% per cycle on average These encouraging results provide novel approaches to designing and fabricating long cycle life cathode in a lithium sulphur battery.
Nor is it clear whether the profiles are stably retained through the lifetime of the individuals.
