The Ubiquitous Chromatin Opening Element (UCOE) technology offers significant advances in recombinant mammalian protein expression. Unlike traditional vectors, UCOE-containing vectors have the capacity to ease the process of isolating cell line clones that express high-levels of recombinant proteins. UCOE sequences promote reproducible and stable high level expression of a linked gene by altering chromatin structure to a transcriptionally permissive state that negates epigenetic-mediated (e.g. DNA methylation) silencing. CET 1019 contains the 3 kb mouse Rps3 UCOE and the 1.5 kb fragment of human HNRPA2B1-CBX3 UCOE. CET 1310 contains the 8 kb fragment of human HNRPA2B1-CBX3 UCOE. CET 1316 contains the 4 kb fragment of human HNRPA2B1-CBX3 UCOE. ReferencesAntoniou, M., et al..
