KANEKA KanCapA™


KANEKA KanCapA™ is a alkaline stable protein A affinity resin suitable for industrial scale purification of monoclonal antibodies. The Protein A ligand is a C-domain based pentamer that exhibits high alkaline stability and negligible Fab binding.

Benefits

> Alkaline stability and long lifetime
> High flow rate operation and easy to scale up from pilot to process
> Track record of successful mAb GMP manufacturing for clinical trial materials

Performance

Alkaline Stability and Long Life Time

KANEKA KanCapA™ ‘s ligand exhibits superior resistance to sodium hydroxide cleaning. The resin can be safely used up to 300 cycles with 0.1 M sodium hydroxide as the CIP solution with 15 minutes of contact time maintaining its binding capacity.

Contact time to NaOH in all experiments is 15 minutes. Ligand leaching less than the detection limit (1 ppm) is plotted as 1 ppm.

Mild Acidic Elution Conditions for All mAbs

KANEKA KanCapA™ ‘s ligand binding ability to Fab region was eliminated in order to use mild acidic conditions for monoclonal antibody elution.

KANEKA KanCapA™ improves the elution profile of the VH3-encoded mAb purification compared to other commercially available Protein A resins. 5 mg/mL-resin of IgG are loaded and elution is performed at pH 3.5 and 3.0. Strip solution is 1 M Acetic acid.

High Binding Capacity

KANEKA KanCapA™ has been designed for efficient antibody capture achieving a high binding capacity at 4 to 6 minutes residence time.

High Flow Rate operation and Easy Scale Up from Pilot to Process

Due to its matrix KANEKA KanCapA™ resin is perfectly suited for pilot and large scale purification processes. It can be efficiently packed into columns of various sizes either by normal flow or by axial compression methods. Packed columns show excellent pressure/flow rate characteristics and excellent performance.

The pressure/ flow rate characteristics and packing efficiency of packed columns, from 4.4 cm to 60 cm I.D. and 20 cm to 25 cm bed height.
The pressures generated by packed beds are calculated by subtracting the system pressure from total pressure.
