    摘要: The invention teaches the use of an addressable nanoscale device to create a programmable substrate useful in selectively attracting proteins, nucleating protein crystals and growing protein crystals of a size amenable to diffraction analysis. Further taught is the use of nanoscale assemblies to create charge patterns, where such charge patterns are useful in purifying, nucleating or crystallizing protein molecules. Charge extension moieties, including water, are taught. The invention provides rapid and efficient identification, purification and detection of proteins and protein-related complexes.

    摘要: Immobilized bioactive protein compositions are prepared containing a bioactive protein such as an enzyme intercalated into galleries of a phyllosilicate, and a crosslinking compound crosslinking the phyllosilicate and the bioactive protein. The phyllosilicate may contain sodium or alkylammonium ions and be montmorillonite. The protein may be lipoxygenase, and crosslinking compounds include tetramethyl orthosilicate, tetraethoxy silicate, propyltrimethoxy silicate, polydimethylortho silicate and methyltrimethoxy silicate. The composition is prepared by delaminating a sodium-saturated phyllosilicate, mixing a bioactive protein with the delaminated phyllosilicate and crosslinking with a crosslinking compound. After crosslinking, the composition may be vacuum dried and ground. The composition can also be prepared by delaminating a montmorillonite, saturating the delaminated montmorillonite with sodium ions, mixing the resultant montmorillonite with an enzyme, adding tetramethyl orthosilicate, allowing crosslinking, and drying. Activities of up to 170% of free protein are achieved using the immobilized bioactive protein compositions, and the compositions retain up to 98% original activity after being stored at room temperature for two weeks.

    摘要: Functionalized fluorescent nanocrystal compositions and methods for making and using these compositions are disclosed. The compositions are fluorescent nanocrystals coated with at least one material. The coating material has chemical compounds or ligands with functional groups or moieties with conjugated electrons and moieties for imparting solubility to coated fluorescent nanocrystals in aqueous solutions. The coating material provides for functionalized fluorescent nanocrystal compositions which are water soluble, chemically stable, and emit light with a high quantum yield and/or luminescence efficiency when excited with light. The coating material may also have chemical compounds or ligands with moieties for bonding to target molecules and cells as well as moieties for cross-linking the coating. In the presence of reagents suitable for reacting to form capping layers, the compounds in the coating may form a capping layer on the fluorescent nanocrystal with the coating compounds operably bonded to the capping layer.
