Verification of representative inserts. a Flanking junctions of an insert from chromosome 22 into ENPP2 on chromosome 8 in Tumour 7396. b PCR across four representative inserts, of elements denoted Chr X_B, Chr 6, Chr 7 and Chr 14 respectively. Note that in addition to the larger, tumour-specific band in most cases there is an intermediate size band, most clearly in the last example. c sequence of insert in a, showing target site duplication (TSD), insert of chromosome 22 material and polyA tail
