Protein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

The Ceres Nanosciences Nanotrap® Protein particles utilize affinity capture and size exclusion to attract and bind low abundance proteins, while excluding unwanted high abundance and high molecular weight interfering molecules.
The Affinity Removal LC Column - Human Albumin is designed to chromatographically remove the most interfering high-abundance protein (albumin) from human samples (e.g., plasma, serum, urine, or cerebrospinal fluid). They are compatible with most FPLC or HPLC pumps or instruments, including Agilent 1200/1100 instruments.
Agilent AdvanceBio SEC columns ensure easy, fast, and accurate quantitation for mAb aggregation and fragment analysis. AdvanceBio SEC offers two different particle sizes, 2.7 and 1.9 µm.
Agilent Bio SEC-3 HPLC columns are a breakthrough technology for size exclusion chromatography (SEC). They are packed with spherical, narrowly dispersed 3 µm silica particles coated with a proprietary hydrophilic layer.
Agilent Bio SEC-5 HPLC columns are packed with 5 µm silica particles coated with a proprietary, neutral, hydrophilic layer for maximum efficiency and stability. Our specially designed packing also promotes high pore volume, improving both peak capacity and resolution.
Agilent ZORBAX GF-250 and GF-450 size exclusion (gel filtration) columns are for size separations of proteins and other biomolecules. The separation range is 4,000-900,000 for globular proteins when using GF-250 and GF-450 columns in series.
Agilent Bio Ion-Exchange HPLC columns are packed with polymeric, nonporous, ion-exchange particles. Bio Ion-Exchange Columns are designed for high resolution, high recovery and highly efficient separations of peptides, oligonucleotides and proteins.
Thorough characterization of monoclonal antibodies includes the identification and monitoring of acidic and basic isoforms. The Agilent Bio MAb HPLC columns feature a unique resin specifically designed for high-resolution charge-based separations of monoclonal antibodies.
PL-SAX for Biomolecules is ideal for the anion-exchange HPLC separations of proteins and deprotected synthetic oligonucleotides under denaturing conditions.
PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation-exchange functionality.
