   Sammanfattning : A highly dealuminated form of zeolite FAU, ultra-stable zeolite Y (USY), was used as an adsorbent matrix in the purification of proteins. Undesired proteins were removed from a crude preparation by adsorption on USY, increasing the purity of an unadsorbed protein (horse radish peroxidase), or the protein of interest was adsorbed on the zeolite and subsequently eluted through changes in the solution conditions (hen egg lysozyme, mouse-immunoglobulin G).

   Sammanfattning : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. LÄS MER
