  • Publication number: 20020010318
    Abstract: The present invention relates to the pulmonary administration of a therapeutic protein by means of powdered pharmaceutical compositions suitable for inhalation therapy. In particular the invention relates to dry powder formulations of secretory leukocyte protease inhibitor (SLPI) for pulmonary delivery. Exemplary pharmaceutical compositions contain SLPI and a pharmaceutically acceptable carrier in the form of a dry powder which is typically less than about 10% by weight water. About 50% to 95% by mass of the powder comprises particles or agglomerates of particles having a diameter within the range of from about 1.0 microns to about 8 microns, with a mass median diameter ranging from about 3.0 microns to about 6 microns.

  • Patent number: 5690963
    Abstract: A process and medium are disclosed for the lyophilization of cells, specifically red blood cells and platelets, and cell-like matter, which comprises the use of solution including a carbohydrate, and biocompatible polymers to permit reconstitution of transfusably useful cells which are viable by the measure of ATP and 2,3 DPG.

  • Patent number: 5466781
    Abstract: A process is described for producing M-CSF from bacteria. It includes: fermentation of bacteria containing M-CSF DNA; harvest of the fractions that contain the M-CSF protein (refractile bodies); primary recovery of the protein; solubilization and denaturation of refractile bodies; M-CSF refolding; purification by column chromatography and other methods; and formulation of the properly refolded M-CSF. This method is advantageous over prior methods in terms of yield and purity.
