Abstract
A chemically synthesized 15 amino acid peptide designated peptide 1-69, which has the sequence of amino acids numbers 308 to 322 (RIQRGPGRAFVTIGK) of the human immunodeficiency virus-1 (HIV-1) IIIB env-coded protein, was used to immunize animals. Peptide 1-69 elicited in immunized animals antibodies that block HIV proliferation and block HIV-induced cell fusion in cell culture.
