Abstract
Structural parameters of lyophilized hemocyanin oligomers from Octopus vulgaris have been obtained by continuous small-angle X-ray scattering experiments using a high-performance area detector realized at Frascati Laboratories on an Adone wiggler beam line. The new apparatus allowed fast collection of two-dimensional diffraction patterns and showed in real-time graphic display both the presence of different scattering units with superparticles of very high molecular weight and the anisotropic effects. The results of the experiments on lyophilized half-met hemocyanin derivative have stressed the fundamental presence of the 19S fraction.
