Patent
Meridian and greenovation Biotech | Date: 2010-05-24

The invention relates to a monoclonal antibody or derivative or fragment thereof that is derived from a parental monoclonal antibody, that recognizes the Lewis Y antigen, characterized in that the Fc region or region equivalent to the Fc region of said antibody or derivative or fragment thereof carries a bi-sected hybrid type N-glycosylation pattern and that said antibody shows at least 10 fold increased ADCC and at least 10% reduced CDC activity.


Patent
greenovation Biotech | Date: 2015-05-28

The present invention relates to an antibody preparation comprising modified antibodies of an animal or derivatives or fragments thereof, specific for an antigen, characterized in that the antibodies or derivatives or fragments thereof comprise an N-glycan structure free of fucose and xylose, and at least 90%, preferably at least 95%, more preferred at least 99%, most preferred at least 100% of the modified antibodies, derivatives or fragments thereof lack a C-terminal lysine residue.


The invention relates to a kit for the combined use for the treatment of cancer patients, which set comprises an antigen of a cellular surface protein, or an antibody directed against the cellular surface protein, and an antigen of an aberrant glycosylation, or an antibody directed against the aberrant glycosylation. This kit is destined both for the immunotherapeutic and the diagnostic application. The invention further relates to a selection method for selecting suitable tumor-specific antigens with the assistance of this kit and corresponding specific antibody preparations.


Patent
greenovation Biotech | Date: 2013-04-17

The invention relates to a method for producing a recombinant protein in cells with a cell wall, comprising the step of increasing the secretion of the recombinant protein through the cell wall by expression of the protein in the cells in a culture medium containing a combination of a surface-active polymer and monovalent metal ions and with an osmolarity at least 0.32 osmol/L, said invention further relating to culture media and nutrient mixtures for the method.
