Abstract

A protocol to obtain CHO cells synchronized in mitosis is described. The synchronized population contained hardly any S-phase cells as judged by the incorporation of 3H-TdR. In these cells a very low frequency of chromatid-type aberrations compared with chromosome-type aberrations was induced by X-rays at 1.5 h after the synchronization.

摘要

本文描述了一种获取处于有丝分裂同步化的中国仓鼠卵巢(CHO)细胞的实验方案。通过掺入³H-胸腺嘧啶脱氧核苷(³H-TdR)判断,同步化细胞群体中几乎不含任何S期细胞。在同步化后1.5小时,用X射线照射这些细胞,诱导产生的染色单体型畸变频率与染色体型畸变频率相比非常低。
