1.1 Basic Principles of Ion-Exchange Chromatography With its origins dating back to the 1940s, ion-exchange chromatography (IEC) was designed specifically for the separation of differentially charged or ionizable molecules (1, 2) . Ion-exchange chromatography refers to the separation of proteins based on charge. Columns can either be prepared for anion exchange or cation exchange. Columns can either be prepared for anion exchange or cation exchange.

PDF A positively charged protein domain, denoted Zbasic, can be used as a general purification tag for purification of recombinantly produced target proteins by cation-exchange chromatography. The first allows easy isolation of the protein by ion-exchange chromatography in a single step (a modification of the procedure of Ref 4), while the second en- sures the clear-cut qualitative analysis by SDS-polyacrylamide electrophoresis.

Purification of Antibodies Using Ion-Exchange Chromatography Purification of Antibodies Using Ion-Exchange Chromatography Kent, Ute M. 1999-01-01 00:00:00 Ion-exchange chromatography is a rapid and inexpensive procedure employed to purify antibodies parti from different sources and species ( … I loaded 300–400 mL into the ion exchange column, but did not recover the protein on elution. I only get the protein when washing in the reverse direction with NaOH where I can see a peak in AKTA, but SDS-PAGE only showed a smeared lane, so I am unable to analyze it.

Ion exchange chromatography definition (or ion chromatography) is a process that allows the separation of ions and polar molecules based on their affinity to the ion exchanger. It can be used for almost any kind of charged molecule including large proteins, small nucleotides and amino acids. Another significant application of ion-exchange chromatography is as a step in the purification of proteins. Some of the substituent groups of amino acids are charged (the total charge for a particular protein is a function of the pH of the solution), which makes ion exchange a suitable method for protein purification.

Methods of lysozyme isolation ‐ ion‐ exchange chromatography • A cation exchange resin can be stirred with egg white until the 15/05/2010 · Ion-exchange chromatography is one of the most common procedures for protein purification. It relies on the charge-charge interactions between the proteins in the lysate and the charges immobilized on the ion-exchange resins. The resins are of two types: cation and anion-exchange. If the net surface charge of the proteins is positive, they bind to the cation-exchange …

Protein Purification by Ion-Exchange Chromatography. Ion exchange protein purification is possible because most proteins bear nonzero net electrostatic charges at all pHs except at pH=pI (isoelectric point). In many biochemistry laboratory manuals [3, 4] gel filtration (molecular exclusion or gel permeation) chromatography and ion exchange chromatography are demonstrated with different proteins. In other laboratory manuals [ 1 , 5 , 6 ] only a single method is demonstrated.
