Zusammenfassung:The invention relates to a method for determining the clonality of a master cell bank (MCB) in which a transgene has been inserted. The method involves a combination of sequencing methodology 5 and bioinformatic analysis, performed on multiple subclones originating from a common MCB, to establish a reliable set of reference transgene insertion regions in one reference subclone, and corresponding sets of comparative transgene insertion regions in one or more other subclones originating from the same MCB. Based on the degree of congruity between reference and comparative transgene insertion regions, the MCB is determined to be either monoclonal or 10 polyclonal. 20008800_1 (GHMaters) P108785.AU.1
