Animal cells ? the breakthrough to a dominant technology

RasAmplification in BHK-21 Cells Produces a Host Cell Line for Further Rapid Establishment of Recombinant Protein Hyper-producing Cell Lines

“…However, the low productivity of animal cells still remains a major obstacle for mass-producing recombinant proteins. 1) To enhance cellular productivity, many researchers have concentrated their efforts to develop a high expression vector containing a potent promoter/enhancer. 2) However, this approach has not been totally successful in raising cellular productivity to commercially desirable levels.…”
