Using the monoclonal antibody MA-01, which recognizes a 210-kDa protein in cell-free extracts, spindle and cytoplasmic microtubules were visualized in budding yeast, Saccharomyces cerevisiae. In additional, a spot-like staining was found beneath the

The structure of (E)- and (Z)-methylcyanovinyl sulphone has been determined by gas electron diffraction and by X-ray crystallography. Considerably widened bond angles in the Z-isomer indicate steric repulsions across the CC bond. The conformer occ
