Isoelectric focussing

Beckman Coulter introduces advanced isoelectric focussing (IEF) technology, featuring a new peptide-based pI Marker Kit
for the charge heterogeneity analysis of biotherapeutics. Based on capillary electrophoresis methods, this solution enables
biopharmaceutical researchers and technicians to easily implement quantitative isoelectric focusing in a QC environment. Using this solution is like looking at IEF through a new pair of glasses,” said Mark Lies, product manager at Beckman Coulter. “We’re able to achieve high resolution and quantitative
reproducibility from molecules that were previously difficult to analyse.” Beckman Coulter has taken a holistic look at capillary isoelectric focusing (cIEF) and optimised system performance for those parameters that are critical for quantitative reproducibility.
