In order to construct the recombinant expression vector and establish the stable SW480 cell line for expression of HIV-1 Nef gene,HIV-1 Nef gene was amplified from the plasmid of p NL4-3 by PCR,and its full ORF was cloned into p EBMulti-neo-myc vector to form the vector p EB-myc-nef. This vector expressing Nef and myc proteins was confirmed by sequencing analysis. The transient expression of Nef in SW480 cells transfected with the recombinant plasmid via LipofectamineTM2000 was then determined by Western Bl...
