One of the type I IFNs of triploid hybrid of gold fish and allotetroploid (3nIFNa) was cloned and characterized, which possesses much stronger disease-resistance ability than its parents.
The mRNA transcription levels of 3nIFNa were obviously increased in all selected tissues after SVCV or GCRV infection.
EPC cells treated with 3nIFNa-containing conditioned media or transfected with plasmid expressing 3nIFNa before SVCV or GCRV infection showed much enhanced antiviral ability.
