摘要

Polypeptides which include at least one antigenic and/or immunogenic determinant group of the envelope protein (env) of the HIV-2 virus, and the preparation thereof by recombinant DNA technology, and the DNA sequences, expression vectors and transformed single-cell organisms used in this process are described. Also described are processes for detecting HIV antibodies or HIV viruses in human sera or other biological fluids.
