Figure 4From: Use of different but overlapping determinants in a retrovirus receptor accounts for non-reciprocal interference between xenotropic and polytropic murine leukemia virusesBinding and interference properties of cloned AKR6 SU and 1E SU. (A) LAPSN(AKR6env) and LAPSN(10A1env) vector titers were measured on dunni cells and dunni cells infected with replication-competent AKR6 or 1E viruses. Data shown are means ± SD of at least two independent experiments with duplicate determinations in each experiment. (B) Binding of 1E-SU-IgG to dunni cells and to dunni cells infected with replication-competent viruses. (C) Binding of Ampho-SU-IgG to dunni cells infected with 4070A amphotropic virus. Data in (B) and (C) are from a representative experiment and show data from ~18,000 live cells (cells that exclude propidium iodide) per histogram.Back to article page
