A novel lectin SML-2 consisting of 138 amino acids was isolated from cyst merozoites of S. muris and sequenced by Edman degradation and mass spectrometry. Crystals diffracting to 2.1 Å resolution at a synchrotron were grown by the hanging-drop vapour-diffusion technique.

Direct slit-collimation correction of small-and wide-angle scattering data from semicrystalline materials on the basis of Akima polynomials and slit functions renders Soller-slit collimation unnecessary. A gain factor of four or five in scattered intensity results.
