【Abstract】 Objective To construct the replication-deficient recombinant adenovirus coding sCR 1 gene before the studies of gene transfection to cardiac muscle of transplanted heart.Methods The sCR 1 -pAxCAwt was constructed by inserted the cDNA of interest into the SwaI site of pAxCAwt.Results The right direction of the insert was confirmed by restriction.Conclusion The direction of the insert must be confirmed by restriction analysis,and the DNA package protein is much helpful during the transfection of the recombinant cosmid to E.coli.
