A material comprising positively and negatively charged nanoparticles, wherein one of said nanoparticles contained a magnetically responsive element, are combined with a support molecule, which is a long natural or synthetic molecule or polymer to make a magnetic nanoparticle assembly. When the magnetic nanoparticle assembly is combined with cells, it will magnetize those cells. The magnetized cells can then be washed to remove the magnetic nanoparticle assembly and the magnetized cells manipulated in a magnetic field.

The invention in suitable embodiments is directed to replacement therapeutics. In one aspect, a medicament is comprised in whole or in part of one or more clathrin heavy chain protein that is formed from a plurality of isolated, synthetic or recombinant clathrin protein molecules. In one embodiment, a man-made clathrin heavy chain protein composition replaces and/or modifies cell elements or processes, in vivo or in vitro, thereby treating a disease, condition, or disorder comprising at least one of cell.

The invention in suitable embodiments is directed to purified non-cage clathrin protein compositions. In one aspect, one or more purified non-cage clathrin protein composition, formed in whole or in part from isolated, synthetic and or recombinant amino acid residues, forms a composition to repurpose at least one aspect of a medicament or use thereof when the medicament is formulated with the non-cage clathrin protein.

The invention in suitable embodiments is directed to using purified, non-cage clathrin protein for purposes of assisting in drug discovery and development. In one aspect, a tool composition, formed in whole or in part from isolated, synthetic and or recombinant amino acid residues comprising in whole or in part one or more protein sequence, forms one or more type of tool for carrying out various elements and activities of drug discovery and development.

The invention in suitable embodiments is directed to purified clathrin protein therapeutics. In one aspect, one or more purified clathrin protein therapeutic composition, formed in whole or in part from isolated, synthetic and or recombinant amino acid residues comprising in whole or in part one or more clathrin heavy chain protein and isoforms thereof, forms one or more type of therapeutic agent for treating various types of a cancerous disease, condition, or disorder in vivo or in vitro.
