细胞内结垢的机制仍然难以捉摸。非洲爪蟾胚胎提取物的使用越来越普遍,以阐明细胞器大小调节的机制。该方法描述了胚胎提取物制备和一种新的核结垢测定法,通过该测定可以确定核大小调节的机制。

该程序的总体目标是使用非洲爪蟾卵和胚胎提取物来产生一种检测方法,其中大细胞核缩小得更小。这种方法可以帮助回答有关核细胞生物学的关键问题,例如调节核大小的机制是什么?该技术的主要优点是非洲爪蟾无细胞提取物的组成和活性很容易纵以评估核大小的事实。

根据文本方案制备非洲爪蟾卵提取物、脱膜精子和组装的细胞核后,将青蛙放在可重复使用的玻璃培养皿上,收集新鲜产下的卵。通过对泄殖腔附近的下背部施加轻柔的压力来促进产卵。将盘子支撑在大约 45 度的位置,让鸡蛋沿着盘子的边缘聚集。
