Abstract

Total cytoplasmic polyadenylated RNA was isolated from the human lymphocyte cell line Wil2 by oligo(dT)-cellulose chromatography. Tritiated complementary DNA (cDNA) was transcribed from the RNA and used as a probe for in situ hybridization to metaphase chromosomes. The majority of G-negative or lightly staining bands were found to be preferential sites of hybridization.

摘要

通过寡聚(dT)-纤维素色谱法从人淋巴细胞系Wil2中分离出总细胞质多聚腺苷酸化RNA。用该RNA转录出氚标记的互补DNA(cDNA),并将其用作中期染色体原位杂交的探针。发现大多数G阴性或浅染带是优先杂交位点。
