Fig. 4From: Duck enteritis virus UL21 is a late gene encoding a protein that interacts with pUL16UL21 structural protein verification. Virions purified from DEF cells were separated by SDS-PAGE, transferred to PVDF membranes, and probed with antibodies against the UL21 protein and β-actin. Total mock-infected or infected cell lysates were also included as antibody controlsBack to article page
