Titration of lentiviral vectors onto restricting cells. Two-fold serial dilutions of HIV-eGFP were titrated onto 10⁵ OMK cells (A), LLC-MK2 (▴) and FRhK4 (●) cells from rhesus macaque (B). (C) Two-fold serial dilutions of SIV-LacZ were titrated onto OMK (●), FRhK4 (▴), and LLC-MK2 (■) cells. Two-fold serial dilutions of HIV-eGFP (●) or SIV-eGFP (▴) were titrated onto African green monkey CV1 cells (D) or rabbit SIRC cells (E). Results are representative of two independent experiments. Lines are guides for slopes of 1 and 2.
