Features and Benefits

• High Capacity removes more interfering abundant proteins
• High Specifity ensures you see an accurate and more complete proteome
• Buffer systems are compatible with 2 dimensional electrophoresis so there are no intermediate time consuming steps that might result in protein loss

General description

The ProteoPrep^® Immunoaffinity Albumin and IgG Depletion Kit has been designed to specifically remove albumin and IgG from human serum (25-50 μl) in preparation of samples for proteomics analysis, two-dimensional electrophoresis (2DE) or liquid chromatography (LC). The ProteoPrep Immunoaffinity medium in the prepacked spin columns is a mixture of two beaded mediums containing recombinantly expressed, small single-chain antibody ligands, resulting in low non-specific binding and high capacity.This kit is also effective in depleting albumin and IgG from mouse and guinea pig serum.
