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.
摘要
已发现来自苏云金芽孢杆菌苏云金变种的β-外毒素苏云金素A在褐家鼠的骨髓细胞中具有C有丝分裂作用。因此，这种外毒素似乎是核学研究中用于中期阻断的一种潜在工具。δ-内毒素蛋白没有类似活性。
