Cell Removal Technique Could Lead to Cheaper Drugs

By Drug Discovery Trends Editor | August 26, 2008

Researchers at the University of Edinburgh have discovered a new way to remove dead cells from cell cultures used to make protein-based drugs. Such drugs are increasingly prescribed to treat a range of illnesses but are expensive. The high costs result from the time-consuming and labour-intensive nature of developing them in cell culture.

Scientists have streamlined this process using magnetic beads coated with special antibodies. The antibodies bind to dead cells without harming the remaining healthy cells. A magnet is then used to draw the dead cells out, leaving the living cells to produce beneficial proteins more effectively.

Researchers have found that removing dead cells can increase productivity of cell cultures by more than 100 per cent. The technique replaces lengthy and potentially damaging methods of cell removal, such as spinning cultures around at high speeds, which can traumatise healthy cells. The technology could also have implications for vaccine development and stem cell research.
