Fig 1: Aggregation and activity of citrate synthase after desiccation, in the presence of nematode LEA protein or BSA. Aggregation is measured by light scattering (apparent absorbance at A340); enzyme activity is assayed according to standard methods and results expressed as percentage of control activity. One drying cycle corresponds to vacuum drying (without freezing) for 1 h followed by immediate rehydration in water to the original volume. Results after two and four drying cycles are shown. See Goyal et al. (2005) for more detail.
