Superdex 200 Increase SEC column, 10/300 GL

Overview
Superdex™ 200 Increase size exclusion (also referred to as gel filtration) chromatography columns are well suited for high-resolution analysis and small-scale purification of monoclonal antibodies (mAb) and other biomolecules with Mr~ 10 000 to ~ 600 000.

•Enhanced performance: improved resolution and runtime compared to predecessor Superdex™ 200.
•Very high resolution: small bead size and narrow particle size distribution provide high resolution, for high protein purity.
•High flow rates: rigid beads give excellent pressure/flow properties.

“Increase”: Cytiva's size exclusion chromatography columns
Superdex™ 200 Increase is a next-generation, dextran-agarose composite matrix for SEC. With smaller and more rigid beads than their predecessors, Superdex™ Increase columns deliver higher resolution purification in shorter run times.

A range of pre-packed columns is available to suit a variety of preparative and analytical applications (Table 1-1).

Selectivity for small-scale purification and analysis of monoclonal antibodies
Superdex™ 200 Increase has a selectivity curve optimized for excellent resolution of antibodies and macromolecules within the range Mr ~ 100 000 to ~ 300 000. It is well suited for detection and separation of antibody monomers, dimers, and aggregates present in monoclonal antibody preparations.

The outstanding resolving power of this resin facilitates protein characterization, including analysis of antibody size variants, assessment of membrane protein size homogeneity, and the study of protein-protein interactions.

Superdex™ 200 and Superose™ 6 analysis ranges are complementary
Superdex™ 200 Increase is optimized to give high resolution separation for proteins with molecular weights in the range Mr ~ 100 000 to ~ 300 000. Superose™ 6 Increase provides a complementary fractionation range, resolving very large protein complexes and macromolecules that Superdex 200 Increase cannot separate.

Cleaning-in-place (CIP) capabilities
This agarose-based resin is alkali-resistant and supports cleaning-in-place (CIP) procedures. This capability allows the same column to be used for different proteins, with minimal risk of carry-over between samples.

Regular cleaning can also increase column lifetime.
