Figure 2. Identification of mVIS.
Strategy outline for identification of regions flanking DNA methylated viral integration sites (mVIS) within murine leukemias. Genomic DNA was digested with DpnII (step 1), followed by methylated DNA immunoprecipitation (MeDIP, step 2). MeDIP enriched fragments were ligated (step 3) and amplified using primers within the LTR (step 4). These fragments were hybridized on a DNA promoter array (step 5). Hypergeometric Analysis of Tiling Arrays (HAT) was used to identify regions flanking mVIS (step 6).
