Stable Cell Line Construction

To create stable cell lines is a key method in reducing the production costs of biopharmaceuticals. We use a modified FRT/Flp-In recombinase system to produce human proteins in CHO cells and 293 cells for stable expression. We have pre-selected CHO cell lines [and 293 cell lines] that contain a single stably integrated FRT site at a transcriptionally active genomic locus and we have proven that they can produce high level expressers of recombinant proteins. We have also developed a unique series of high-yield vector system, in which two GC-rich regions flanking the gene expression cassette makes the promoter and enhancer continuously exposed to transcriptional machinery by preventing chromatin condensing. This revolutionary ground-breaking technology allows the available highest yields in all common mammalian cell protein production host cell lines, such as 293, CHO and NSO.
