Seeds were prepared by crushing former crystals. 0.2 µl of seed crystals was added into the precipitant solution containing the growing protein crystals. The mixture solution was … WebThe structure and symmetry of quasiperiodic crystals can be described by embedding them into a higher-dimensional space as lattice periodic structures. Their intersection with the physical space gives the real structure, shifting the physical space parallel to the original one gives another possible realization of the crystal with the same energy.
