Bioactive protein-containing nanoparticle composition and method for producing the same
摘要:
PROBLEM TO BE SOLVED: To provide a sustained-release composition that does not cause abnormal response at an administration site and maintains persistent activity of the contained bioactive protein or peptide when a predetermined amount of a bioactive protein or peptide is administered.
SOLUTION: The bioactive protein-containing nanoparticle composition comprises a bioactive protein or peptide, a water-soluble carbonate, a water-soluble phosphate and a water-soluble zinc salt with one another to form nanoparticle precipitates. The water-soluble zinc salt is added such that the compositional ratio of bioactive protein: the water-soluble zinc salt in a weight ratio is in the range of 1:0.2-1:3.5. The bioactive protein or peptide is G-CSF, hGH, interferon, erythropoietin or midkine.
