  GPEx® Advantage: The High Yield Solution
 
Higher Speed HIgher Yield Higher Versatility
   
  The GPEx® gene insertion technology produces mammalian cell lines - typically CHO or 293 (HEK) cells - that deliver higher yields of target proteins than any conventional system based on transfection or electroporation.

One reason for these higher yields is that the GPEx® retrovector targets high-expressing chromosomal matrix attachment sites in the target cell genome, leading to markedly higher expression of the gene in transduced cells compared with other systems. Another important reason is that the optimization of GPEx® cell lines employs an iterative insertion process that drives up the inserted gene copy number and proportionally increases protein expression levels. The optimized cell line may therefore have a dozen or more copies of the desired gene, all stably inserted and expressing the target protein.
