The present invention relates to a package for storing, mixing, resuspending and dispensing sterile or non-sterile solutions or suspensions and comprises a sterilizable bag having fittings which provide for the introduction and exit of fluids and solids, as well as means for resuspending and stirring the fluids. Additionally, structural support means are provided for shipment, filling and dispensing. Unlike conventional stainless steel equipment, the system is disposable, does not require cleaning, provides for safe, rapid and accurate resuspension of suspended solids and can accommodate a wide range of liquid volumes.

Disposable storage, transport and resuspension system

A process for converting lipid-containing bacterial capsular polysaccharide, such as lipo-polyribosyl ribitol phosphate, lipo-PRP, into lipid-free, endotoxin-free polysaccharide, such as polyribosyl ribitol phosphate, PRP, by solubilizing polysaccharide-containing powder derived from culture media of bacteria, such as Haemophilus influenzae type b, cleaving covalently bound fatty acids from the polysaccharide, and removing the lipids, and endotoxin.

Process for converting lipid-containing bacterial capsular

A process for removing endotoxin from Gram-negative polysaccharides such as H. influenzae polyribosylribitol phosphate by adding alcohol incrementally until substantially all lipopolysaccharide precipitates.

Process for removing bacterial endotoxin from gram-negative

A process for removing endotoxin from Gram-negative polysaccharides such as polyribosylribitol phosphate by solubilizing polysaccharide-containing powder derived from Gram-negative bacteria fermentation broth to provide a divalent counter ion for endotoxin and adding alcohol incrementally to induce lipopolysaccharide precipition, and mixing material resulting from the alcohol addition with a nonionic resin, a detergent and a chelating agent.
