  • Publication number: 20140335127
    Abstract: A system and a method for the production of recombinant N-glycosylated target proteins. The system comprises a prokaryotic organism (e.g. Escherichia coli) into which is introduced a genetic information encoding for a metabolic apparatus capable of carrying out the requested N-glycosylation of the target protein. Said prokaryotic organism also contains the genetic information required for the expression of one or more recombinant target proteins. The metabolic apparatus preferably comprises specific glycosyltransferases for the assembly of the oligosaccharide on a lipid carrier and an OTase that covalently links this oligosaccharide to specific residues of the desired protein.

  • Publication number: 20090279454
    Abstract: The invention relates to a method for creating a DHCP network device configuration, wherein the parameter allocation by a DHCP server is performed using Option 82, and the assignment for the IP address to be allocated to a network device is determined on the basis of the topological information. The topological information is provided to the DHCP server by the requesting device and a DHCP relay agent, and the relay agent acts on each DHCP message sent by a device in the network by means of an additional DHCP Option 82 and sends the messages via unicast to the DHCP server, whereas the standard DHCP message is forwarded. According to the invention, a network device sends, in addition to the regular DHCP discovers via MAC broadcast, DHCP messages via MAC multicast to a MAC multicast address, and from this MAC multicast sends unique information via unicast to the DHCP server by means of a DHCP relay agent, since the associated network device filters the multicast.
