Use of quasi-isoelectric buffers as anolyte and catholyte to improve capillary isoelectric focusing performances.

The use of quasi-isoelectric anolytes and catholytes has been investigated to improve CIEF performances. Narrow pH cuts of carrier ampholytes (NC) have been compared to more conventional couples of anolytes/catholytes (phosphoric acid/sodium hydroxide and glutamic acid/lysine). First, a CIEF setup that consists in a bare silica capillary and 70:30 water… CONTINUE READING
