Lepta SP HR is a high-resolution strong cation-exchange chromatography resin that takes advantage of differences in the nature and magnitude of charge of different molecules under specific conditions to separate them. This chromatographic resin can be well used for the separation and purification of various biological molecules such as recombinant proteins, antibodies, nucleic acids, viruses and virus-like particles, and polysaccharides. Compared with traditional strong cation exchange chromatography resin, Lepta SP HR exhibits superior performance:

(1) The improved Lepta base frame is more rigid, so it can achieve higher process flow rate at lower back pressure and improve process efficiency.

(2) Increase the dynamic binding capacity of the chromatography resin by upgrading the ligand coupling method.

(3) Finer particle size improves the resolution of the chromatographic resin.
