GENERATION AND USE OF FAB, SCFV, AND RELATED BINDING MOLECULES SPECIFIC FOR HIV-1 REV

摘要

Described herein is the identification, though phage display, of a chimeric rabbit/human anti-Rev Fab (SJS-R1) that readily solubilized polymeric HIV-1 Rev. The Fab binds with very high affinity to a conformational epitope in the N-terminal half of HIV-1 Rev. The corresponding single chain antibody (scFv) was also prepared and characterized. Methods of making and using SJS-R1 Fab and SJS-R1 scFv, and antibodies and antibody fragments that share at least one CDR with SJS-R1 Fab, are provided. Specific described methods include methods of preventing or reversing polymerization of HIV Rev, methods of preventing or inhibiting replication of a lentivirus in a cell, methods of reducing infectivity of replication of a lentivirus, inhibiting Rev function in a cell infected with a lentivirus, and methods of treating a disease or symptom associated with Rev expression in an animal.
