Cation exchange resins are polymer based media developed for the separation of biomolecules including monoclonal antibodies and peptides.

TOYOPEARL CM-650 is a weak cation exchanger for biomolecule purification. It is available in three grades and can be used for high throughput capture, intermediate purification, and polishing process steps.

TOYOPEARL® SP-650 is a strong cation exchanger for preparative purification. It can be used for initial, intermediate, final purification process.

TOYOPEARL® SP-550 is is a strong cation exchanger useful for preparative purification of insulin and proteins with molecular weights up to 100,000. It is used for initial refining process.

TSKgel SP-5PW is a strong cation exchanger for preparative purification. It is a small particle size filler for final purification process and high performance separation process.

TOYOPEARL® GigaCap CM-650 is a highly adsorptive cation exchanger for protein purification. Suitable for initial purification (capture) process and intermediate refining process, it shows a high adsorption amount for a wide range of samples such as antibodies, general proteins, peptides etc. It shows different selectivity from S (SP) type cation exchanger.
