Integrase and LTR attachment site mutant vectors.(A) Integrase mutants derived upon mutation of the HIV-1 pol gene within the packaging plasmid, pMDL. Depicted are the locations of the c-terminal deletion and core domain point mutations. (B) LTR attachment site mutants derived upon deletion of the LTR attachment sites within the transfer vector, pcDNA-CS-CGW. Depicted are the locations of the 12 bp U3 (5’-ACTGGAAGGGCT-3’) and 11 bp U5 (5’-TCTCTAGCAGT-3’) attachment (att) site deletions. (C, D) Gag capsid protein (p24) was measured by ELISA in supernatants from 293T cells transfected with a GFP (C) or bleomycin resistance transgene containing transfer plasmid (D). Data is represented as mean ± SD.
