Study on biodegradable microspheres containing recombinant interferon-alpha-2a.


In this work, a new microsphere delivery system comprising calcium alginate microcores surrounded by a biodegradable poly-DL-lactide-poly(ethylene glycol) (PELA) coat was designed to improve the loading efficiency and stability of peptide drugs. Recombinant interferon (IFN)-alpha-2a, used as a model peptide drug, was efficiently entrapped within the… (More)
