Next, we conducted single cell gel electrophoresis (SCGE) assays to determine whether heat, cold and freezing altered hemocyte...

... not survive freezing. The supercooling point of cold-acclimated (cold tolerant) snails (–6.6±0.8°C) did not differ significantly from that of non-acclimated ones(–7.1±1.5°C) under laboratory conditions. Furthermore, snails died even under more moderately low temperatures approaching 0°C. These results...

... individuals showed no intraspecific significant differences in supercooling points and ice formation. Although this might suggest that metabolic and biochemical preparation are non-essential prior to subzero temperature exposure, the increased survival rate with slower cooling rates gives evidence...
