Imaged capillary isoelectric focusing (icIEF)

Charge-variant separation that focuses proteins at their isoelectric point along a pH gradient inside a capillary and images the focused bands directly with a camera, compressing analysis from hours to minutes.

Where it's used

Capillary electrophoresis for biopharma
Capillary-based separation instruments — CE-SDS purity assays, imaged capillary isoelectric focusing (icIEF) for charge-variant analysis, CE-mass spectrometry, and microfluidic chip electrophoresis for nucleic-acid fragment sizing — that replace slab-gel electrophoresis with automated, higher-resolution biopharma characterization and QC.
