PAM gene copy numbers for 154 ZFN clones from CHO Der2 parental cell line transfected using ZFN mRNA. The two clones (K62 and K68) identified as knocked-out for all PAM gene copies at the genomic DNA level. The copy number was determined by qPCR, and the data are means ± standard deviations of two technical replicates.
