Abstract: New conjugates in which a glycoprotein and a nucleic acid binding substance are connected by the carbohydrate moiety of the glycoprotein can be used to import therapeutically or gene-therapeutically efficacious nucleic acids into cells which express on their surface a protein to which the glycoprotein binds. The preferred glycoprotein is transferrin, the preferred nucleic acid-binding substance is a homologous polycationic polypeptide such as polylysine. The conjugates can be prepared by oxidizing the carbohydrate group of the glycoprotein, in particular, sialic acid, to the aldehyde form and coupling it with the nucleic acid binding substance, which preferably contains amino groups. Complexes containing the conjugates and an efficacious nucleic acid are ingredients of pharmaceutical preparations for therapeutic or gene-therapeutic application.
Patent DE-4117250-A1 (DE)
IPC: B30B11/04
Filed: 1991-05-27
Abstract: The invention relates to an adapter plate for simple insertion in and removal from a conventional axial press. Using the adapter plate, an axial press is extended by use of wobble-pressing technology, so that both customary pressing methods can be carried out together in one axial press. The design features of the adapter plate are based on complete separation of the drive assembly for the wobble press by the adapter plate. In this way, both pressing methods can be used together even where it has previously been necessary to forego one of the two pressing techniques, mainly because of the high investment costs. <IMAGE>
