ProteoSolve-IEF is designed to solubilize many types of proteins during sample preparation for a variety of analytical techniques, including isoelectric focusing (IEF) and gel- or solution-phase protein fractionation. This reagent contains powerful chaotropic agents and a zwitterionic detergent. ProteoSolve-IEF is shipped dry. Reconstitute with distilled or HPLC-grade water. The kit also contains ion exchange resin, for applications where ion exchange of the IEF reagent is required.
