Abstract:
The present invention relates to a novel virus, said virus belonging to the HIV-2 family of viruses. In particular, the invention relates to a retrovirus characterized by being antigenically more similar to, but genetically distinct from, HIV-2/ROD and SIVMAC than to HIV-1. More particularly, the present invention relates to the isolation and cultivation of HIV-2/ST thereby providing a source of said virus and its derivatives including virus-derived antigens and derivatives and parts thereof, useful in the development of diagnostic assays for said virus or other related viruses belonging to the HIV-2 family. Furthermore, the present invention is also directed to recombinant DNA molecules containing the entire HIV-2/ST provirus thereby providing a source of recombinant viral components useful in the development of said diagnostic assays for HIV-2 viruses. The present invention is also directed to antibodies specific to viral components and to different antibodies specific to the first antibodies, said antibodies are also useful in the development of diagnostic assays for HIV-2 viruses. The present invention also contemplates a method of the isolation of HIV-2/ST-type viruses.
