[The detection and sequence analysis of the simian T-lymphotrophic retrovirus (STLV-1 Papio) by using the polymerase chain reaction].

: The gene amplification technique was used for detection and sequence analysis of STLV-1 Papio proviral DNA. The polymerase chain reaction was performed with a primer pair at tax region of HTLV-1, 7336-7354, sense strand, and 7516-7494, antisense strand. One microgram of DNAs isolated from LUG-4 cells and autopsies was used in a reaction volume of 50 microliters involving 30 cycles of amplifications. The reaction product was blunt-end cloned into pUC19 cut with Smal. The sequence was done with T7-polymerase using 32P-dATR as a label. Our results indicate that STLV-1 Papio provirus is actually present in the cells of a lymphoid cell line and tumor cells of lymphomatous monkeys. There are some differences between STLV-1 Papio and reported sequences of HTLV-1 and STLV-1.
