New protein separation technology
... U-M professor of chemistry, liquid phase has many advantages over gels. "The process takes hours instead of days. It can handle large quantities of protein and detect trace amounts of protein," Lubman says.

Organic gels have a problem doing this, Han explains, because the strands must stretch out into a long, snakelike form to get through the pores of the gel, but then ...New research animals earn their stripes
