  • Publication number: 20160095907
    Abstract: A device, system and method for producing glycosylated proteins in plant culture, particularly proteins having a high mannose glycosylation, while targeting such proteins with an ER signal and/or by-passing the Golgi. The invention further relates to vectors and methods for expression and production of enzymatically active high mannose lysosomal enzymes using transgenic plant root, particularly carrot cells. More particularly, the invention relates to host cells, particularly transgenic suspended carrot cells, vectors and methods for high yield expression and production of biologically active high mannose Glucocerebrosidase (GCD).

  • Publication number: 20050260715
    Abstract: 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.

  • Patent number: 6127144
    Abstract: An aminopeptidase inhibitor is used when expressing heterologous protein in a bacterial host, such as Streptomyces. Use of such an inhibitor inhibits degradation of the heterologous protein by aminopeptidases. Inhibitors are designed based upon the mechanism and substrate specificity of the target protease and expressed protein.
