What is the purpose of chromatography in protein analysis?

Points on purpose of chromatography in protein analysis:

• Proper protein separation is necessary before identification, purification, and functional studies.
• By isolating individual proteins from complex biological mixtures, separation ensures that analytical methods measure a single protein rather than a mixture of overlapping biomolecular signals.
• Through well-resolved protein fractions, researchers can confidently perform identification, purification, and functional experiments without interference from coexisting proteins.
