An Estimation of the Density of Water in Artemia Cells
This paper is part of a long-range research program on the properties and roles of water in the cells of Artemia cysts1,2. Each cyst is a mass of about 4000 cells surrounded by a shell, most of which can be chemically removed3. This system is a useful model for such studies because the cells are capable of repeated cycles of dehydration-rehydration in a fully reversible way. Thus, one can measure a given property as a function of cell water content in viable animal cells. The cysts are available in large amounts, and details of their ultrastructure, biochemistry and biophysics are available3. In the present case I describe measurements of cyst density as a function of cell water content, and evaluate these data in terms of the density of intracellular water. A preliminary account has been published4.
