FIG 5 — Analysis of Env-receptor binding affinity through blocking assay of viral entrance and coimmunoprecipitation. (a) Expression of various mutant Env proteins and β-actin in the lysates of DF-1 cells transfected with different plasmids. (b) The blocking ability of various pCAGGS-Env vectors on ALV-J replication and the wide-type was regarded as the standard. (c) Detection of the affinity of receptor NHE1-ECL1-rIgG binding with various mutant Env proteins through coimmunoprecipitation. Env protein and β-actin in the cell lysates were regarded as references.
