  • Patent number: 11307122
    Abstract: The invention relates to the preparation of biological cells for the mass spectrometric analysis of cellular properties such as taxonomic classification, antibiotic resistances, response to drugs or other active substances, and others. The cells can be prokaryotic or eukaryotic microorganisms which have particularly been cultivated directly on a mass spectrometric sample support, or eukaryotic cells from tissues or cell cultures. The invention proposes that the cells are not disrupted by adding matrix solution for a subsequent ionization by matrix-assisted laser desorption (MALDI), but that they are disrupted in a separate treatment step using acids and/or solvents on the sample support itself. Surprisingly, the cell proteins released then adhere to the sample support so that they can be carefully washed with buffer solution to remove salts and other soluble impurities which can stem from earlier treatment steps, for example from nutrient solution.

  • Patent number: 11253483
    Abstract: A method for intracellular delivery of single proteins or other cargo molecules by encapsulation within nanocapsules formed by interfacial polymerization of one or more types of monomers and selected protease cleavable cross-linkers is provided. The thin positively charged capsules are readily brought into the cytosol of target cells by endocytosis. The capsules are degraded by the action of endogenous proteases or co-delivered proteases on the cross-linkers releasing the functional cargo unaltered. The cross-linkers can be adapted to be cleavable by specific enzymes selected from available intracellular enzymes within the target cell or co-delivered or self-cleaving when the cargo itself is a protease. The nanocapsules produced by the methods have been shown to have long-term stability, high cell penetration capability, low toxicity and efficient protease-modulated specific degradability without affecting cargo protein function.

  • Patent number: 11224643
    Abstract: A streamlined method for purifying alpha-1-antitrypsin (AAT) from an AAT-containing protein mixture, such as Coh fraction IV precipitate, is provided. In the method of the invention, contaminating proteins are destabilized by cleavage of disulfide bonds with a reducing reagent, such as dithiol, which does not affect AAT. The destabilized proteins are then preferentially adsorbed on a solid protein-adsorbing material, without the addition of a salt as a precipitant. Separation of the solid absorbent from the solution leaves a purified AAT solution that is directly suitable for chromatographic purification, without the need for extensive desalting as in prior art processes. A process incorporating this method, which provides pharmaceutical grade AAT in high yield on a commercial scale, is also described.
