Electrophoresis is utilized in many scientific disciplines to separate, enrich and purify biomolecules which differ in their electrical charge state. Agilent Technologies was one of the first to introduce a capillary electrophoresis system to the market. Ever since Agilent Technologies is leading the field by innovating electrophoretic applications. Microfluidic Lab-on-a-Chip technology applies the principle of electrophoresis to networks of channels and wells etched into glass or polymer chips. The new Agilent 3100 OFFGEL Fractionator resolves proteins of peptides by isoelectric point (pI) to achieve high resolution pI-based fractionation.
