title: [The use of the vif gene expression product of HIV-1 in bacteria for detecting specific antibodies in the sera of infected persons].
abstract: A fragment of the genome of human immunodeficiency virus type 1 (HIV-1) coding for p23 protein, the product of vif gene, was cloned in a plasmid vector pUR291. The resulting recombinant plasmid pLacVif1 was conducive in E. coli cells to the synthesis of a hybrid polypeptide with molecular weight of 136 kDa containing antigenic determinants of p23 protein of HIV-1. The employment of this polypeptide for analysis of HIV-1-positive sera by indirect enzyme immunoassay showed that vif-specific antibodies were found in 53% of the cases and their appearance was not related to the stage of the disease.
