HiTrap SP XL are strong cation exchangers prepacked with SP Sepharose XL media, optimized for fast, convenient small-scale protein capture using ion exchange (IEX) chromatography.

• High binding capacities with high flow rates
• Convenient and affordable for fast, easy separations either alone or connected in series
• Designed for use with syringe, peristaltic pump, or chromatography system such as ÄKTA design

Q Sepharose XL and SP Sepharose XL resins have long chains of dextran coupled to a robust, 6% highly cross-linked agarose matrix. The dextran chains increase the exposure of the Q or SP charged groups, which results in very high loading capacities.
