Ion Exchange Chromatography (IEC) - A gradient pushed separation primarily based on the cost of the protein and its relative affinity for custom amino acids manufacturer the chemical spine of the column. Previous to reaching their pI, protein mobility also relies upon upon measurement, conformation, steepness of pH gradient, and the voltage gradient. The protein might be eluted in a lowering salt gradient, with the most hydrophobic proteins eluting from the column final. Two-dimensional Gel Electrophoresis - A type of electrophoresis wherein proteins are separated first in one route by cost adopted by a measurement separation in the perpendicular route.
