How to use rapid gel filtration in protein purification

Learn how gel filtration columns use porous beads made from agarose or dextran to separate proteins by size. Smaller proteins enter the bead pores and elute last, while larger proteins bypass the beads and elute first.

Explore the advantages of short Superdex 75 and 200 5150 GL columns that enable fast, powerful analytical separation while reducing sample dilution compared to traditional large-format gel filtration.

Use rapid gel filtration columns to analyze target protein purity after purification steps like imidazole elution and to identify antibody dimers and aggregates in under 15 minutes without denaturing samples.

Apply Superdex 5150 GL columns to rapidly test different buffer conditions and imidazole concentrations, identifying optimal elution conditions while minimizing consumption of expensive buffers and sample.

Screen multiple detergents using rapid gel filtration analysis directly after membrane protein solubilization, using only 10 microliters of sample per run to assess homogeneity and prevent crystallization while conserving expensive detergents.

Determine size distribution and complex formation of interacting proteins quickly using the speed and flexibility of short gel filtration columns for rapid characterization of protein complexes.
