Protein fractionation, in-solution recovery Prefractionation of proteins and peptides prior to LC/MS analysis can dramatically increase the number of proteins ultimately identified. The Agilent 3100 OFFGEL Fractionator uses a novel isoelectric focusing technique to achieve excellent pI-based fractionation. The resulting fractions are in solution, making recovery for LC/MS analysis much easier than with old-fashioned gels. Results are highly reproducible, and the Agilent 3100 OFFGEL Fractionator is now even easier to use with its new web-based user interface.
