Immunological study of the nef protein from HIV-1 by polyclonal and monoclonal antibodies
1991
We constructed and expressed different overlapping fusion proteins with the nef gene of HIV-1 and generated specific polyclonal rabbit and monoclonal mouse antibodies against these recombinant proteins. The rabbit antisera, one of the monoclonal antibodies as well as a serum from a HIV-1 infected patient recognized the nef protein with Mr 27 kDa in latently HIV-1 infected glioma cells in the immunoblot. In contrast, these antibodies could not detect nef in productively HIV-1 infected Molt-3 cells neither in immunoblot nor in indirect immunofluorescence assays. These results indicate the possible participation of nef in viral latency.
