34µm TopGF 200 Agarose Gel Filtration Media
SHBC TopGF 200 is a high-resolution agarose gel filtration medium with an average particle size of 34µm.
It is developed for size exclusion separation, purification and analysis of monoclonal antibodies, large proteins, protein complexes and other biological macromolecules.
The fine particles provide efficient mass transfer, sharp chromatographic peaks and reliable polishing performance.
Product Overview
TopGF 200 is an agarose-based size exclusion chromatography resin designed for preparative protein purification.
Its porous and hydrophilic matrix separates biomolecules according to hydrodynamic size. The non-binding separation mechanism helps maintain protein structure and biological activity.

How TopGF 200 Works
TopGF 200 separates biomolecules according to their size and ability to enter the pores of the resin particles.
Large molecules have limited access to the internal pores and pass through the column more quickly. Smaller molecules enter more pores and elute later.
This size-based mechanism does not require a specific ligand or strong adsorption, providing gentle conditions for sensitive proteins.
Recommended Applications
Monoclonal Antibody Purification
Suitable for preparative separation, purity improvement and polishing of monoclonal antibody products.
Antibody Aggregate Removal
TopGF 200 can separate antibody monomers from dimers, oligomers and high-molecular-weight aggregates.
Protein Fragment Removal
Suitable for removing degradation fragments and low-molecular-weight protein impurities.
Large Protein Purification
Can be used for large recombinant proteins, enzymes, fusion proteins and other macromolecular protein products.
Protein Complex Separation
Suitable for separating protein complexes, oligomers and biomolecular assemblies according to size.
Biologic Drug Polishing
Can be used after affinity or ion exchange chromatography to improve final product purity.
Product Formulation
Suitable for protein sample cleanup, buffer-condition evaluation and formulation process development.
Quality Control Research
Can be used to evaluate protein aggregation, degradation, purity and molecular-size distribution.
Advantages of 34µm GF200 Media
High Separation Resolution
The fine 34µm particles form a uniform packed bed and improve separation between proteins with similar sizes.
Efficient Aggregate Removal
The porous matrix supports separation of antibody monomers from dimers and larger aggregates.
Sharp Chromatographic Peaks
Controlled particle size helps reduce peak broadening and produces concentrated target fractions.
Low Nonspecific Adsorption
The hydrophilic matrix reduces unwanted protein interactions and supports high sample recovery.
Gentle Purification
Size exclusion chromatography does not require harsh binding or elution conditions.
Suitable for Polishing
TopGF 200 is designed for purification stages where final product purity and aggregate removal are important.
TopGF 200 vs. TopGF 75
Feature | TopGF 75 | TopGF 200 |
|---|---|---|
Average Particle Size | 34µm | 34µm |
Main Target | Medium-sized proteins | Antibodies and large proteins |
Typical Application | Recombinant protein purification | Antibody polishing |
Aggregate Removal | Protein systems | Antibody and large-protein systems |
Separation Mode | Size exclusion | Size exclusion |
Main Advantage | Protein resolution | Large biomolecule resolution |
TopGF 75 is recommended for medium-sized recombinant proteins. TopGF 200 is more suitable for monoclonal antibodies, large proteins and protein complexes.
General Operating Procedure
Mix the resin slurry gently before use.
Remove the storage solution.
Wash the resin with purified water or equilibration buffer.
Prepare a uniform slurry.
Pack the chromatography column under controlled flow or pressure.
Equilibrate the packed bed with running buffer.
Clarify and filter the sample.
Apply the sample at the optimized flow rate.
Elute using the selected running buffer.
Collect and analyze the target fractions.
Clean and store the resin according to the validated procedure.
Sample volume, bed height, flow rate and buffer conditions should be optimized for the target protein and required resolution.
Column Packing Recommendations
Fully suspend the resin before packing.
Avoid introducing air bubbles.
Use filtered and degassed buffers.
Select a column frit suitable for 34µm particles.
Keep the slurry concentration uniform.
Do not allow the packed bed to dry.
Avoid sudden pressure changes.
Monitor column backpressure.
Evaluate packing efficiency before purification.
