    New! Protein Purification Services

    Do you have a protein purification challenge?

    If so, then consider twin column counter-current chromatography schemes. These advanced protein purification techniques can increase purity without sacrificing purity. Yields of more then 98% with >95% recovery.
    No need to be an expert. Athena Enzyme Systems™ offers cost-effective bioseparation services using the Contichrom® CUBE Twin Column Chromatography System.

    Isolation of Pure Protein from Complex Mixtures

    The MCSGP (Multi-column Counter-current Solvent Gradient Purification) enables the isolation of pure protein from complex mixtures with >90% step yields and >95% purity. No need for multiple separation steps.

    Purify Grams of Material Overnight

    The CaptureSMBâ„¢ processes can be used purify 1 gram of IgG using two 1 ml Protein A columns or a His-tagged protein using IMAC. The process can be applied to any affinity purification and is particuarly suited for separations requiring the use of expensive resins.

    Integrate the Capture Step with a Polishing Step

    The Integrated Batch mode of the twin column system can be used to perform the capture and polish step in a seamless two-step process. No need to collect product inbetween steps and then reload.

    Purify Low Abundance Molecules without HPLC

    The N-Rich® process is a counter-current separation technique that uses a cyclical process to enrich for a low abundance target molecule. Can be used on any separation process employing a gradient elution.
