Methods are disclosed for sterilizing biological materials to reduce the level of one or more active biological contaminants or pathogens therein, such as viruses, bacteria (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria,, rickettsias), yeasts, molds, fungi, prions or similar agents responsible, alone or in combination, for TSEs and/or single or multicellular parasites. The methods involve sterilizing biological materials containing one or more non-aqueous solvents with irradiation.

Methods for sterilizing biological materials containing non-aqueous solvents

Methods are disclosed for sterilizing preparations containing albumin to reduce the level of one or more active biological contaminants or pathogens therein, such as viruses, bacteria (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria, chlamydia, rickettsias), yeasts, molds, fungi, prions or similar agents responsible, alone or in combination, for TSEs and/or single or multicellular parasites. These methods involve sterilizing preparations containing albumin, such as plasma protein fractions, with irradiation.

Methods for sterilizing preparations containing albumin

Methods are disclosed for sterilizing biological materials to reduce the level therein of one or more biological contaminants or pathogens, such as prions, responsible for the disease states known as transmissible spongiform encephalopathies (TSEs) in mammals. These methods involve sterilizing biological materials with irradiation.

Methods are disclosed for sterilizing tissue to reduce the level of one or more active biological contaminants or pathogens therein, such as viruses, bacteria, (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria,, rickettsias), yeasts, molds, fungi, spores, prions or similar agents responsible, alone or in combination, for TSEs and/or single or multicellular parasites. The methods involve sterilizing one or more tissues with irradiation.

Methods for sterilizing biological materials by irradiation over a temperature gradient

Methods are disclosed for sterilizing biological materials to reduce the level of one or more biological contaminants or pathogens therein, such as viruses, bacteria (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria, chlamydia, rickettsias), yeasts, molds, fungi, single or multicellular parasites, and/or prions or similar agents responsible, alone or in combination, for TSEs.

Methods for sterilizing biological materials by multiple rates

The present invention introduces a class of compounds, 2-substituted carbonyl compounds, that are useful as disinfecting agents, and particularly useful in methods for the disinfection of biological fluids. Members of the class of compounds have been found to possess pathogen inactivating properties against a variety of pathogens. The compounds and methods disclosed herein are useful for disinfecting biological fluids such as blood and blood fractions, among others.

Method of inactivating pathogens

The present invention relates to the preparation and use of liquid formulations of plasma proteins, particularly blood coagulation factors. More specifically, the present invention relates to stable liquid formulations of Factor VIII and Factor IX that can be administered by injection or infusion to provide a constant level of the coagulation factor in the blood.

Methods of production and use of liquid formulations of plasma proteins

This invention is directed to the preparation and utilization of supplemented chitin hydrogels, such as chitosan hydrogels. Further provided are biomaterials comprising same. The particular supplement delivered by the chitin hydrogel is selected as a function of its intended use. In one embodiment, this invention provides a composition of matter, comprising a chitin hydrogel or chitin-derived hydrogel, wherein the hydrogel does not inhibit full-thickness skin wound healing.

Chitin hydrogels, methods of their production and use

The present invention is directed to pathogen inactivating compositions that can be used to disinfect various biological fluids, such as blood, blood fractions, and the like. The compositions are suitable for disinfecting biological fluids containing valuable, but labile, components such as proteins without destroying the desired properties of such components. The pathogen inactivating compositions of the present invention are produced by contacting water or an aqueous solution with iodinated matrix material. The compositions can be pre-formulated and stored for subsequent use in disinfecting a wide range of biological fluids.

Pathogen inactivating compositions for disinfecting biological fluids

The present invention provides media for inactivating pathogens found within protein-containing biological fluids. The media of the present invention preserve the structural integrity and biological activity of labile proteins while simultaneously exhibiting potent disinfectant activity. The media of the present invention comprise iodinated chromatographic media, particularly ion exchange media. The invention further provides methods for disinfecting biological fluids.
