Hydrodynamic diameter of fish antifreeze molecules by quasi-elastic light scattering

Measurements are reported of the hydrodynamic diameter of two classes of fish antifreeze molecule determined by quasi-elastic light scattering, as a function of temperature from 18 degree C to -2 degree C. The smallest antifreeze glycopeptide AFGP8 from the Antarctic nototheniid Dissostichus mawsoni...

Description
Summary:Measurements are reported of the hydrodynamic diameter of two classes of fish antifreeze molecule determined by quasi-elastic light scattering, as a function of temperature from 18 degree C to -2 degree C. The smallest antifreeze glycopeptide AFGP8 from the Antarctic nototheniid Dissostichus mawsoni was found to reduce in size as the temperature was lowered. The Type 111 antifreeze peptide, Ab1, from the Antarctic zoarcid Austrolycicthys brachycephalus did not change diameter when cooled.
