Abstract
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.
