    Abstract:
    Recombinant proteins derived from immunodominant conserved domains of HIV-1 env and gag genes were synthesized in E. coli. An immunoblot system using total cell lysates was employed for the analysis of recombinant bacterial clones. Together 427 serum samples obtained from asymptomatic anti-HIV seropositive individuals, AIDS patients, healthy donors and persons suffering from various conditions were comparatively evaluated for the presence of HIV-1 antibodies using recombinant peptides and commercially available western blot (WB) and ELISA assays. The recombinant antigen product of plasmid pEX41 was found to be superior, with respect to sensitivity and specificity, to the viral gp41 which represents a diagnostically important constituent of the WB.
