Change of crystallins from water soluble into insoluble with ageing of rat;

At present, more and more macromolecule polymers have been used as carriers on the research and preparation of insoluble bactericides which are the developing hotspots in the recent years, but inorganic carriers have been involved rarely.

By using the low - ion buffer and high - ion buffer, the soluble and insoluble PGIP were obtained through ammonium sulfate precipitation, CM - Sepharose FF and Sephadex G - 100 chromatography.
