    摘要: Endogenously produced cationic antimicrobial peptides are ubiquitous components of host defenses in mammals, birds, amphibia, insects, and plants. Cationic peptides are also effective when administered as therapeutic agents. A practical drawback in cationic peptide therapy, however, is the cost of producing the agents. The methods described herein provide a means to efficiently produce cationic peptides from recombinant host cells. These recombinantly-produced cationic peptides can be rapidly purified from host cell proteins using anion exchange chromatography.

    摘要: The subject invention provides a method for recovering a solution containing purified, enzymatically active Cu-Zn superoxide dismutase or a polypeptide analog thereof having substantially the same amino acid sequence as, and the bioloical activity of, naturally-occurring Cu-Zn superoxide dismutase from a composition which comprises cells containing Cu-Zn superoxide dismutase or a polypeptide analog thereof. The invention also provides a method of increasing the yield of recovered solutions having an increased concentration of b isoform of an enzymatically-active polypeptide analog of Cu-Zn superoxide dismutase from a composition which comprises cells containing a, b and c isoforms of the polypeptide analog.
