Monoclonal antibodies against the minimal DNA-binding domain in the carboxyl-terminal region of human immunodeficiency virus type 1 integrase.

abstract：:Cloned avian leukosis viral DNAs were mutagenized in the long terminal repeat, in the leader sequence for env mRNA, and at the poly-env junction. The effect of these mutations in the viral DNA upon its ability to direct virus production or env mRNA synthesis was analyzed by microinjecting the mutant DNAs into chicken ...
