Avian leukosis virus Subgroup J (ALV-J) is a retrovirus which infects
meat-type chickens. Envelope glycoprotein of ALV-I determines the host
range of virus infection and cross-neutralization patterns. Env genes of ALV-J
were amplified by PCR from CEF infected with ADOL-4817 and ADOL-Hcl, and cloned into E. coli TA vector. The senquence analysis showed the env
gene of ADOL-4817 is 1746 bp, which can be transla...
