MLV integration sites in human K562 cells
Integration sites of murine leukemia virus (MLV) in human K562 cells, enriched via ligation-mediated PCR (LM-PCR). Each sequence fragment contains the 3' LTR of MLV, human genomic DNA indicating the integration site, and the linker+barcode used for LM-PCR. Sequences are paired-end reads; for a given fragment, one read will begin with the LTR, and the other should begin with the linker. The first four bases after the LTR are the MLV integration site.
