Abstract

A rapid and specific technique to detect polyriboadenylic acid sequences in RNA is described. The method depends upon the ability of RNAs that contain poly(A) sequences to associate specifically with poly(U) that has been immobilized on fiberglass filters by ultraviolet irradiation. A high proportion of the transcripts synthesized in vivo and in vitro from the vaccinia virus genome contain poly(A) sequences and bind to the poly(U) filters. Similarly, DNA-like RNA from the nucleus and from the cytoplasmic polyribosomes of HeLa cells is rich in species that bind to poly(U) filters. Poly(U) immobilized on cellulose powder is useful to make columns with a high capacity for the binding and purification of poly(A)-containing RNAs.

摘要

本文描述了一种快速且特异的检测RNA中多聚腺苷酸序列的技术。该方法基于含有多聚(A)序列的RNA能够与通过紫外线照射固定在玻璃纤维滤膜上的多聚(U)特异性结合的能力。从痘苗病毒基因组在体内和体外合成的转录本中,很大一部分含有多聚(A)序列并能与多聚(U)滤膜结合。同样,来自HeLa细胞核和细胞质多核糖体的类DNA RNA富含能与多聚(U)滤膜结合的种类。固定在纤维素粉末上的多聚(U)可用于制备具有高容量结合和纯化含多聚(A)RNA的柱子。
