摘要: Disclosed is a method for purifying Interleukin-10 (IL-10). The method is comprised of subjecting an IL-10 containing solution to cation exchange chromatography, anion exchange chromatography, hydroxyapatite chromatography, and gel filtration chromatography. The present invention is also comprised of a process for separating different IL-10 dimers present in a protein fraction from each other by subjecting the protein fraction to hydroxyapatite chromatography. The present invention is also comprised of a process for separating variants of a protein differing in an N-terminal amino acid sequence present in a protein fraction from each other by subjecting the protein fraction to hydroxyapatite chromatography.

摘要: Methods for purifying adenoviruses from a contaminated sample using a hydroxyapatite medium are provided. Sodium chloride concentrations present in buffers used throughout the method are at least 150 mM to prevent the adenovirus from irreversibly binding to the hydroxyapatite. Levels of contaminants and empty adenovirus capsids from samples purified by conventional purification techniques are further reduced to provide a highly pure adenovirus preparation.

摘要: Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.
