ALV-J strain identification by IFA and western blot analysis. The two ALV-J strains isolated from late and fast feathering chicken groups were detected by IFA and Western blot. (A) DF-1 cells infected with M180 strain isolated from late-feathering chicken and K243 strain isolated from fast-feathering chicken showing ALV-J specific green fluorescence, 150x magnification. (B) DF-1 cells infected with M180 and K243 produced specific ALV-J envelope protein blots. Uninfected DF-1 cells were used as a negative control (NC).
