The Protean i12 System for Isoelectric Focusing

The PROTEAN i12 IEF System, from Bio-Rad Laboratories, is used for isoelectric focusing (IEF) of immobilized pH gradient (IPG) strips. The PROTEAN i12 IEF System can simultaneously run up to 12 IPG strips in 12 independently programmed lanes. Watch this video to learn about more unique features and benefits of this system, which can be used for in-gel peptide fractionation prior to LC-MS.
