MAbPac Protein A Affinty Column

MAbPac Protein A Column for Monoclonal Antibody Titer Analysis

The Thermo Scientific™ MAbPac™ Protein A column is a high-performance, affinity chromatography column specifically designed for fast, accurate determination of monoclonal antibody (MAb) concentration in the harvest cell culture (HCC). Early in the development of recombinant MAbs, a large of number of HCC samples must be screened for IgG titer. Affinity chromatography employing a Protein A ligand is often used to determine the MAb concentration. The MAbPac Protein A column is a high-pressure liquid chromatography (HPLC) column designed to provide fast, accurate, titer analysis with linearity over a wide concentration range without carryover.

The MAbPac Protein A column is based on a novel nonporous polymeric resin consisting of a hydrophobic divinylbenzene core and a hydrophilic surface. This proprietary resin is designed for fast mass transfer, resulting in efficient separations without carryover. The recombinant Protein A ligands are covalently attached onto the hydrophilic resin surface through their amine groups to provide a very rugged, reproducible column. The column is available in a HPLC bioinert, 4 × 35 mm PEEK column body.

Product Highlights: 

• A novel nonporous polymeric resin with a hydrophilic surface
• Functionalized with the recombinant protein A ligands
• Wide range of MAb quantitation: 0.025–5 mg/mL
• Fast analysis: 2 min/analysis
• Rugged
• Low pressure: column pressure is less than 250 psi at 2 mL/min

The MAbPac Protein A column can be used for both titer analysis or concentrating and purifying IgG material for later experiments or two-dimensional (2D) chromatography.
