WORKFLOW
Separate proteins from complex mixtures through controlled chromatographic binding, washing and elution.
When selecting products, compare flow range, pressure limits, detection channels, sample loading and fraction-collection configuration.
Use the narrower categories to separate experimental requirements before comparing individual products. Products across this broader branch can serve different steps or use different formats.
FPLC systems
Modular gradient system for laboratory biomolecule purification by affinity, ion exchange, hydrophobic interaction and size exclusion. The cited configuration includes sample pumping and combined fraction-valve/fraction-collector operation. Confirm column fittings and pressure limits for each method. Regulatory intended use is unknown.
Anion-exchange resins
Bulk weak anion exchanger carrying diethylaminoethyl groups. Provides a distinct ligand chemistry from the manufacturer's Q resin; it is not a prepacked purification kit. Buffer pH and conductivity must be selected for the target protein. Regulatory intended use is unknown.
Anion-exchange resins
Bulk strong anion exchanger with quaternary-amine ligands for charge-based biomolecule separation. Supplied as resin rather than a prepacked column. Protein binding conditions and column packing require method development. Regulatory intended use is unknown.
Cation-exchange resins
Sulfopropyl-functionalized bulk agarose for charge-based biomolecule purification. This strong cation exchanger requires column packing and a target-specific binding/elution method. Regulatory intended use is unknown.

ALTERNATIVE DOES NOT MEAN IDENTICAL
Final groups are designed around experimental substitution requirements. Group membership is provisional until the necessary technical details have been verified for the intended experiment.
Start with your application, then verify the technical requirements against each manufacturer’s documentation.
