Abstract

Messenger RNA was isolated from spleen polysomes of rats immunized with sheep red cells, two methods being employed: a sorption of mRNA on on membrane filters, and poly(U)-cellulose affinity chromatography. The rat transplantable lymphosarcoma cells treated with this RNA started hemolysine synthesis which persisted throughout many cell generations in transplantation of the tumor. The probability is discussed of m-RNA not only functioning as a template for antibody synthesis but also deblocating appropriate genes in recipient cells.

摘要

从用绵羊红细胞免疫的大鼠脾脏多核糖体中分离信使核糖核酸(Messenger RNA),采用了两种方法:信使核糖核酸在膜滤器上的吸附以及聚(U)-纤维素亲和层析。用这种核糖核酸处理的大鼠可移植性淋巴肉瘤细胞开始合成溶血素,并且在肿瘤移植后的许多细胞代中持续存在。文中讨论了信使核糖核酸不仅作为抗体合成模板起作用,而且在受体细胞中使适当基因移位的可能性。
