Comparison of antigen capture assays against HIV-1 in evaluating antiviral compounds

Abstract

Five antigen capture enzyme-linked immunosorbent assays (ELISAs) have been assessed for detecting HIV-1 in tissue culture supernatants of cell cultures used routinely to investigate antiviral activity. Although all the ELISAs are very sensitive to low levels of antigens they have different characteristics when used for titrating virus antigens.
