Host atom precipitation
WebPrecipitation Reactions. Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids. WebInitially the hot atom is highly ionized (e.g. for Z = 50 ionic charges up to +20 have been observed). As the hot atom is slowed down to thermal energies, it collides with a number …

WebHost cell proteins are potentially immunogenic and can compromise product integrity during processing and hold-up steps. There is an increasing body of evidence that the type of host cell proteins present in recombinant protein preparations is a function of cell culture conditions and handling of the harvest cell culture fluid. WebDifferential protein precipitation is a rapid and economical step in protein purification and is based on exploiting the inherent physicochemical properties of the polypeptide. …
