  • a Serum samples are from HIV-1-infected individuals.

  • b Titers in MT-2 cells are the reciprocal serum dilutions at which 50% of cells were protected from virus-induced cell killing; titers for primary isolates are the last serum dilutions at which p24 synthesis was reduced >80% relative to the virus control (no test serum).
