Have deletions at RT, IN and Env genes and no wild type virus conversion.
Efficiently infected human primary cells and CD4+ T cell-grafted nude mouse.
Monitory of Gluc activity is simple and more sensitive than anti-p24 ELISA assay.
A safe and valuable HIV-1 infection system for biosafety level-2 laboratory.
