SP Persefose XL is a strong cation exchange chromatography resin that uses the difference in the nature and amount of charge of different molecules under specific conditions to separate them. This chromatographic resin can be used successfully for the separation and purification of various biological molecules, such as recombinant proteins, antibodies, nucleic acids, viruses and virus-like particles, and polysaccharides.

SP Persefose XL features extremely high capacity and high flow rates:

(1) The highly cross-linked agarose base frame has excellent rigidity, so it can achieve high process flow rate under low back pressure and improve process efficiency.

(2) High capacity and high flow rate are suitable for the downstream process capture stage of crude samples.
