Pulsed-field gel electrophoresis has been applied to analyze the karyotypic variability among colpodid ciliates. The 18S ribosomal gene was found at different locations in the electrophoretic pattern, and these size variations in the ribosomal DNA subchromosomal molecule seem to be species specific. This could potentially be a useful new tool with which to differentiate colpodid ciliates.
脉冲场凝胶电泳已被应用于分析结肠纤毛虫的核型变异性。18S 核糖体基因在电泳图谱中的不同位置被发现,而核糖体 DNA 亚染色体分子的大小变化似乎是种特异性的。这可能是一种有用的新工具,可以用来区分结肠纤毛虫。
