    Affinity Purification (36)

    Affinity Purification

    Affinity chromatography is a powerful technique to enrich or purify a protein from other proteins and components in a biological sample like crude cell lysate or other complex samples. The protein of interest is purified by taking advantage of its specific binding properties to an immobilized ligand. Orochem affinity purification products: 1. EZ Link Resin and Kit 2. EZ Pure Protein A Resin and Kit 3. EZ Pure Protein G Resin and Kit 4. EZ Pure Streptavidin Resin and Plate 5. EZ Pure Ni-NTA Resin and Kit 6. EZ Pure Cobalt Resin and Kit 7. EZ Pure Glutathione Resin and Kit
  • Filtration

    Filtration (1)


    The filtration processes are critical steps in the purification of biological molecules once the cells are lysed. Orochem offers following products to effectively remove unwanted cellular debris from biological samples.
    1. Coarse Membrane Spin Filter Orochem’s coarse membrane spin filter cartridges and plates are designed to separate cells or cell lysate from tissue debris through 250 µm mesh filters.
    2. Cell Lysate Filtration Plate Orochem’s cell lysate filtration plate is designed for improved capture and detection of interacting proteins to empower interactomics research.
