Fast Protein Liquid Chromatography (FPLC)
Fast Protein Liquid Chromatography (FPLC) — A preparative-scale liquid chromatography system optimized for protein and peptide purification at moderate pressures, commonly using ion exchange or size exclusion columns.
What Is FPLC?
Fast protein liquid chromatography (FPLC) is a low-pressure liquid chromatography system optimized for peptide and protein purification at laboratory scale. FPLC systems (e.g., AKTA from Cytiva) operate at lower pressures than HPLC (< 40 bar vs. 400 bar), using larger bead sizes (10-90 µm) and flow rates (1-10 mL/min).
Applications
- Affinity: His-tag/Ni-NTA for recombinant peptide capture
- IEX: Charge-based separation and polishing
- SEC: Aggregate analysis and buffer exchange
- Scale: mg to gram purification. Preparative HPLC for larger scale
