Designed for high-resolution protein fractionation at preparative scales. Pre-packed with Superdex™ 200 pg resin, these size exclusion chromatography columns enable purification of mAbs, DNA fragments and other biomolecules with M r ~ 10 000 to ~ 600 000.
Preparative-grade: high purity and resolution
Two column sizes available: for samples up to 5 mL and up to 13 mL
Prepacked columns: convenient and reproducible; can be used with standalone pump or chromatography system
Scalable SEC: resin properties and column dimensions optimized for preparative-scale protein purification; choose from two XK column sizes (16/600 or 26/600)
Compatible with ÄKTA systems: fittings (1/16”) for direct connection to ÄKTA systems and other chromatography systems
HiLoad Superdex 200 preparation grade resin is well suited for rapid, preparative protein purification and scale-up. Its selectivity curve gives a broad fractionation range from Mr~ 10 000 to 600 000, with excellent resolving power for antibody monomers, dimers and contaminants of lower molecular weight, such as albumin and transferrin.
High mechanical strength and hydrophilicity make this dextran-agarose composite resin suitable for larger scale applications that require high flow rates, minimal nonspecific interactions, and fast, effective cleaning-in-place (CIP) protocols.
Successful use of Superdex 200 pg columns in research and process development
Superdex 200 prep grade columns are an excellent choice for many applications, including:
How to scale up column chromatography to process larger sample volumes
When scaling up size exclusion chromatography columns in order to process larger sample volumes in a single step, consider the following steps:
Optimize high-resolution separation at small scale.
Maintain the sample-to-column volume ratio and the sample concentration.
Increase the column volume by increasing the cross-sectional area (inner diameter) of the column.
Maintain the bed height.
Run the separation at the same linear flow rate as used on the smaller column.
