Abstract

Viral DNA of unintegrated closed circular form was isolated from a swine kidney cell line (SKL) which was infected with a porcine retrovirus Tsukuba-1 (PRetV) produced from a swine malignant lymphoma-derived cell line. Shimozuma-1 and cloned using a lambda phage vector, Charon 21A. One of ten independent clones contained the 8.3 kb DNA fragment as an insert, which was thought to be a full length of viral DNA molecule carrying a long terminal repeat (LTR) sequence. We have analyzed this insert by mapping the recognition sites of some restriction endonucleases by Southern blot hybridization with appropriate probes.
