摘要:
A method of precipitating nanostructures out of a mixture of cellular components is disclosed. The nanostructures have an outer surface comprising phospholipids. The method comprises contacting the mixture with an oligo-amine having a sufficient number of amine groups such that it ionically conjugates with said nanostructures.
摘要:
The invention relates to a method of selective separation of target molecules from a heterogeneous mixture of target molecules and non-target molecules in a solution, the method comprising: providing a proteinaceous phase in the solution, wherein the proteinaceous phase comprises a matrix of self-assembling proteins, and wherein the proteinaceous phase selectively absorbs the target molecules into the matrix and/or selectively excludes non-target molecules from the matrix thereby selectively isolating the target molecules from the non-target molecules in the solution. The invention further relates to alternative methods of selective separation of target molecules, methods of ion torrent sequencing, compositions, kits and uses thereof.

摘要:
The invention relates to a protein particle comprising chimeric protein having an aggregating part capable of forming or aggregating into a substantially insoluble protein particle when expressed by a cell; and a functional part capable of binding to, or being bound by, a target compound. Affinity matrixes comprising the protein particle are also provided.
摘要:
A process for the co-precipitation of a substance with a stabiliser therefor, by a gas anti solvent process comprising introducing into a particle formation vessel a supercritical fluid pure or mixed with a modifier; and a solution comprising said substance and said stabiliser dissolved in a solvent; so as said solvent is extracted from the solution by said supercritical fluid and co-precipitation of the substance and stabiliser occurs. The process may be carried out using an apparatus comprising a particle formation vessel (22) and a nozzle (27) having a central orifice (39) serving to introduce a solution of the substance and a plurality of outer orifices (41) serving to carry a flow of supercritical fluid into the particle formation vessel (22), such that the solvent is extracted from the solution by the supercritical fluid and precipitation of micron sized particles of the substance/stabilizer occurs. The substance is preferably a protein of pharmaceutical interest, which is highly stabilized for storage by this process.
