The present invention relates to recombinant expression vectors which express segments of deoxyribonucleic acid that encode recombinant HIV and HCV antigens. These recombinant expression vectors are transformed into host cells and used in a method to express large quantities of these antigens. The invention also provides compositions containing certain of the isolated antigens. , diagnostic systems containing these antigens and methods of assaying body fluids to detect the presence of antibodies against the antigens of the invention.

The present invention relates to a DNA segment encoding a recombinant HIV p24 protein or HIV p24-gp41 fusion protein and a recombinant DNA (rDNA) molecule capable of expressing either protein. Cells transformed with the rDNA, methods for producing the fusion protein and diagnostic methods and systems using the fusion protein are also described.
