WebHere, we have developed and optimised a gentle and simple IgE purification method based on thiophilic interaction chromatography (TIC). IgE binds to the thiophilic resin in presence of 1.2 M ammonium sulfate and is eluted in low salt concentration. Monomericity of purified antibodies ranged between 54 and 73%. WebThiophilic affinity chromatography (TAC) is a powerful and simple method for the purification of proteins—in particular, immunoglobulins. It relies upon the affinity of a …

WebHydrophobic charge induction chromatography is a recently developed method for protein separation based on the use of dual-mode ligands. They are designed in such a way so as to combine a molecular interaction supported by a mild hydrophobic association effect in the absence of salts. WebTherefore, thiophilic adsorption chromatography is very useful for the purification of immuno- globulins (monoclonal and polyclonal antibodies). Albumins are not adsorbed on thiophilic media, which often simplifies the effective separation of antibodies (Fig. 1). Antibodies of the IgM sub-class can also be bound on a Fractogel®EMD TA column.
