Synthetic polymers [5, 51] as well as derivatives of natural macromolecules, such as hydroxypropylcellulose acetate succinate [52, 53] or chitosan [54, 55] have been used. Precipitation can be induced by pH shift, salinity modification or temperature. Certain polysaccharides, such as sodium alginate whose solubility is sensitive both to acidic conditions and to the presence of divalent cations (e.g. Ca ) or carrageenan which precipitates upon decreasing temperature, have not yet been exploited but are eligible candidates for a future use in affinity precipitation. Various works can be selected from the literature to illustrate the basic principles of this technique. [Pg.241]
