How do I pack Protein A resin in a column?

This video explains how to pack a column with our Amsphere™ A3 Protein A resin. It explains the small scale packing in an 1.6cm Diameter Column (HiScale™2 16/40).

2 HiScale™ is a trademark of GE Healthcare.

 

Why use AMSPHERE™ A3?

  • Outstanding Dynamic Binding Capacity

    A highly cross-linked bead structure and controlled attachment of the protein A ligand results in a superior dynamic binding capacity.
    At higher flow rates the semi-rigid bead structure allows to achieve up to 50% higher DBC compared to the market standard product at low to moderate residence times of 2-6 minutes.

  • Impurity Clearance At Industry Standard

    The surface treatment of the polymeric base matrix resulted in low HCP, DNA, virus and aggregate levels that are very similar to hydrophilic backbones such as agarose.

  • Superior Caustic Stability

    Amsphere™ A3 can resist up to 300 cycles with 0.1 M sodium hydroxide as CIP solution (15 minutes of contact time) while maintaining a dynamic binding capacity above 90%. In addition, 0.5 M sodium hydroxide can be used for at least 100 cycles (15 minutes of contact time).

  • Regulatory Compliance

    The manufacturing process of Amsphere™ A3 complies with all regulations that enable the usage of the final product for GMP compliant drug manufacturing. All raw materials including the polymeric beads and protein A ligand are manufactured within ISO certified manufacturing facilities owned by JSR.

    The entire production process is free from animal-derived components and is certified BSE-TSE Free.

    The Regulatory Support File is available under a Confidential Disclosure Agreement (CDA).

  • Pre-Packed Formats & Validated Protein A Leaching Kit

    Ready-to-use pre-packed RoboColumn®s (200 – 600 µL) and small scale 1 mL and 5 mL columns are available for screening purposes and process development. Larger formats including GMP compliant pre-packed columns are also available on request.

    An Amsphere™ A3 ligand specific ELISA kit is available through Cygnus Technologies. Please click here to order the kit.

WEBINAR: FC-FUSION PURIFICATION PERFORMANCE AND MECHANISM ANALYSIS USING AMSPHERE A3

ON DEMAND

Join Ying Yao, JSR’s Applications Scientist, for a webinar on comparative purification analysis of Fc-fusion proteins.

In this webinar, DBC and purification properties of four commercially available Protein A chromatography resins are compared using four Fc-fusion proteins. Significant factors affecting DBC are particle size, binding capacity, and pore diffusion. The analysis of these factors showed how Amsphere A3 was able to out-perform the other three resins for three out of the four molecules tested. Join us to learn about how Amsphere A3 can support your Fc-fusion protein purification!
