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 cahhy-over between samples.
Regular cleaning can also increase column lifetime.
Choose from 3 column sizes
Superdex™ 200 Increase columns are available pre-packed in three different sizes, to suit varying application needs (Table 1-1).
Column | Recommended sample volume | Recommended operating flow | Efficiency (N/m) | Applications |
Superdex™ 200 Increase 3.2/300 | 4 to 50 µL | 0.075 mL/min | >48,000 | High-resolution analysis and purification of small sample volumes, especially when sample amount is limited and low buffer consumption is important. |
Superdex™ 200 Increase 10/300 GL | 25 to 500 µL | 0.75 mL/min | > 48,000 | Standard for high-resolution preparative purification and analysis of small volumes of proteins, especially monoclonal antibodies |
Superdex™ 200 Increase 5/150 GL | 4 to 50 µL | 0.45 mL/min | > 42,000 | Rapid purity check, homogeneity analysis and screening of proteins, especially monoclonal antibodies. |
Successful use in published research
In addition to their use for antibody purification, Superdex™ 200 Increase pre-packed columns are also used in a variety of other applications, including:
structural analysis of Salmonella ATPase ligand-bound states by SEC-MAL
analysis of protein oligomerization states
study of replicative helicase machinery
examination of the structure, assembly, and function of cytoplasmic pore filaments
initiation of pulsed gene expression by LytTR transcription regulators
