Representative PCR and FISH results of HT1080 and B16F10 cells transferred with the modified hChr.21. (a) Representative results of transgene insertion analysed by PCR. (b) Representative FISH images of HT1080 Bsd #06-02 transferred with the targeted chromosome. The rhodamine (red) signal indicates the repetitive sequence of plasmid p11-4 containing human alpha-satellite sequences, which stains the centromeric region of human Chr. 21. The FITC signal (green) indicates the presence of the inserted I-EGFP-I-Bsd-Fcy; Fur vector on the near centromeric region. (c) Representative results of telomere-associated truncation analysed by PCR. (d) Representative FISH images of B16F10 HisD44-01. The rhodamine (red) signal indicates the repetitive sequence of human Cot-1 for staining of whole human chromosome. The FITC signal (green) indicates the presence of pBS-TEL/Dq-HisD vector on the same truncated hChr.21 as observed in the CHO donor cells. Full-length gels of the PCR analysis are presented in Supplementary Figure 2.
