Title:
CHEMICALLY MODIFIED HIV ENVELOPE GLYCOPROTEIN
Document Type and Number:
WIPO Patent Application WO2001049720
Kind Code:
A3
Abstract:
The invention relates to an HIV envelope glycoprotein in a purified form which can be obtained using a method comprising the following steps: (1) obtaining an envelope glycoprotein in a purified form; (2) reducing at least one disulphide bond of the protein from step (1); (3) alkylating at least two free sulfhydryl groups; (4) optionally, oxidizing the remaining sulfhydryl group; (5) denaturing and (6) renaturing. The invention also relates to the use of the inventive modified HIV envelope glycoprotein in a vaccine against HIV which can be used to induce HIV-neutralising antibodies in a human subject for therapeutic or prophylactic purposes.
