Chromatography buffers optimize protein purification and recovery procedures. Eluting from the stationary phase, the solutions change pH levels for a weakened electrostatic force. The salty substances generate and maintain pH levels for proper ion exchange, size exclusion, and affinity. Simply changing the ratio of acid to salt, the chromatography buffer pH level will change accordingly. Designed for various separation techniques, the concentrated liquids or crystalline format options come premade to cut down on prep work time.
