Abstract: The present invention relates to in vitro sialylated human factor H protein or biologically active sialylated fragments or biologically active sialylated variants thereof. The present invention also relates to in vitro methods of producing such proteins and using such proteins in methods of treating complement-mediated diseases such as C3 glomerulopathy, atypical hemolytic uremic syndrome, or age-related macular degeneration.

Abstract: The present invention relates to a lysosomal protein composition comprising a plurality of lysosomal proteins that are potentially diversely glycosylated according to a glycosylation pattern, wherein said glycosylation pattern has at least 45% paucimannosidic N-glycans; a method of manufacturing the lysosomal protein composition in a bryophyte plant or cell, and medical and non-medical uses of the lysosomal protein composition. E.g. the lysosomal protein can be ?-Galactosidase for the treatment of Fabry Disease or ?-Glucoceramidase for the treatment of Gaucher's Disease. The unique glycosylation results in improved therapeutic efficacy—surprisingly even without mannose-6-phosphate that is common for CHO cell produced lysosomal proteins.

Abstract: The invention concerns a method for detaching expressed material from the surface or from the apoplast of plant cells, wherein the plant cells are treated with a rotor-stator in a liquid medium, wherein the specific heat from the rotor-stator introduced by rotation of the rotor is a maximum of 3 kJ per kg of the liquid medium and per g/L dry weight of the plant cells and the specific heat capacity introduced into the medium is a maximum of 1.5 kJ per kg of the liquid medium per minute and per g/L dry weight of the plant cells.
