Research Abstract

Chinese hamster ovary (CHO) cells are the most dependable host cells for the industrial production of therapeutic proteins. We constructed CHO genomic bacterial artificial chromosome (BAC) library from a gene-amplified CHO cell line for genome-wide analysis of CHO cell lines. CHO chromosomal markers were constructed by fluorescence in situ hybridization (FISH) imaging using BAC clones as hybridization probes (BAC-FISH). Using constructed tools, we could analyze chromosome rearrangement in CHO cell line.
