title: Metaphase arrest in the bone marrow cells of Rattus norvegicus by the Beta-exotoxin of Bacillus thuringiensis.
abstract: The beta-exotoxin, thuringiensin A, from Bacillus thuringiensis var. thuringiensis has been found to be C-mitotic in the bone marrow cells of Rattus norvegicus. This exotoxin therefore appears to be a potential tool for metaphase arrest in karyological studies. The delta-endotoxin protein has no similar activity.
