Depositor Comments

During HIV-1 infection, unintegrated viral cDNA may be circularized. The circularization generates a unique junction between the long terminal repeat (LTR) ends. HIV-1 2LTR circles have been quantified as measure of viral replication or entry of the viral cDNA into the host cell nucleus. The amplicon is 2672-2879 in the Addgene sequence file. This corresponds to HIV-1 strain HXB2 reference genome 9585-9719 bp (Addgene 2672-2806 bp) fused to 1 to 51 bp (Addgene 2829-2879 bp). In this plasmid there are 22 bp (Addgene 2807-2828 bp) of random sequence inserted between the HIV-1 ends. The insert may be amplified with primers MH535 (5' AACTAGGGAACCCACTGCTTAAG), MH536 (5' TCCACAGATCAAGGATATCTTGTC), and Taqman probe MH603 (5' ACACTACTTGAAGCACTCAAGGCAAGCTTT).
