Abstract
We established seven hybridoma clones producing monoclonal antibodies (MAbs) against the envelope transmembrane protein (TMP) of a Ghanian isolate of human immunodeficiency virus type 2 (HIV-2[GH-1]) from mice immunized with the detergent-disrupted purified whole virus. The MAbs were found to react with 35 kilodalton (kD) TMP of the HIV-2[GH-1] virus in a Western blot assay (WB). Two of these MAbs recognized 135 kD proteins in addition to TMP in the lysate of HIV-2[GH-1]-infected cells. Two other MAbs cross-reacted with viral components corresponding to TMPs of HIV-2ROD and SIVMAC isolates in a Western blot. Results of competitive binding assay suggest that there are at least three epitopes on a TMP molecule of the HIV-2[GH-1] isolate. The MAbs did not inhibit syncytium formation between HIV-2[GH-1]-infected MOLT-4 cells and MOLT-4 clone 8 cells, nor virus infection to MOLT-4 clone 8 cells.Keywords
