Abstract
The influence of the extraction of hnRNP (informofer) particles on the ultrastructural appearance of the perichromatin granules was studied. The extraction of hnRNP particles was carried out by SAMARINA's procedure from the rat liver nuclear fraction. The extraction did not change the numbers and the general ultrastructural features of perichromatin granules. It is therefore unlikely that the perichromatin granules are the morphological representatives of storaged or transported hnRNA.
摘要
研究了异质性核糖核蛋白（信息传递因子）颗粒的提取对染色质周边颗粒超微结构外观的影响。采用萨马林娜的方法从大鼠肝细胞核组分中提取异质性核糖核蛋白颗粒。提取过程并未改变染色质周边颗粒的数量和总体超微结构特征。因此，染色质周边颗粒不太可能是储存或转运的核内不均一RNA的形态学代表。
