Fast protein liquid chromatography
Template:Infobox chemical analysis Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Fast Protein Liquid Chromatography, usually referred to as FPLC, is a form of column chromatography used to separate or purify proteins from complex mixtures by using Ion Chromatography. It is very commonly used in biochemistry and enzymology. Columns used with an FPLC can separate macromolecules based on size, charge distribution, hydrophobicity, or biorecognition (as with affinity chromatography).

Typical columns
Typical columns
Typical columns used for protein purification include:
- Ion exchange chromatography, cation or anion — separate proteins based on surface-charges
- Size exclusion chromatography, also known as Gel filtration chromatography, Gel permeation chromatography or desalting — separate proteins based on size.
- Reversed phase or hydrophobic interaction — separates based on hydrophobicity which depends heavily on surface area
- Affinity chromatography — columns which purify based on ligand affinity (e.g. a His6-tagged protein purified on a nickel column).
