摘要:
Glycoproteins containing high mannose oligosaccharides are obtained and used to generate antibody to the mannose portion of the molecule. Such antibodies can be used in a diagnostic assay. The glycoproteins can be used to generate neutralizing antibody.

The present invention is drawn to a fusion protein containing at least one binding domain that specifically recognizes an eptitope of a plant pathogen and at least one additional domain made from a protein or peptide sequence which is toxic to the pathogen or detrimental the replication, transmission or life cycle of the pathogen. The present invention is further drawn to a pathogenocide made from the binding domain, a cellular targeting sequence and/or membrane localization sequence that leads to membrane anchoring. The present invention is further drawn to nucleotide sequences encoding fusion proteins and pathogenocides and to vectors containing the nucleotide sequences; as well as methods of making the fusion proteins and pathogencides and methods of making pathogen resistant plants, plant cells, or plant tissues with the fusion proteins and pathogenocides.
摘要:
A method is described for altering the properties such as the accumulation, the stability and/or integrity, the subcellular localisation, the post-translational modifications, the ability to get purified, and the phase partitioning behaviour of natural or recombinant target proteins expressed in a host organism. The method involves the co-expression of natural or recombinant proteins along with a specific binding partner that sequesters the target recombinant protein into a complex. The binding partner is supplied as a separate protein allowing formation of intermolecular complexes or is fused to the protein of interest, allowing the formation of intramolecular complexes. The binding partner can also be used to alter the subcellular localisation without modifying the sequence or structure of the target protein itself. This can be achieved by either incorporating appropriate targeting signals into the binding ligand, which are then linked to the target protein through complex formation, or complex formation itself may alter the subcellular localisation. The same strategy can be used to provide an affinity tag to facilitate protein purification. The principle of the invention is demonstrated by the coexpression of an unstable antibody and its cognate antigen.

The invention provides a method for the generation of a monoclonal plant cell line from a heterologous population of plant cells, comprising the following steps: (a) provision of a heterologous population of plant cells; (b) preparation of protoplasts from said heterologous population of plant cells; (c) separation of single protoplasts by subjecting the preparation of protoplasts to flow cytometric sorting; (d) regeneration of a separated single transformed protoplast until the formation of a microcolony by co-cultivation in the presence of feeder cell material; (e) removal of the microcolony from the feeder cell material and cultivation of the microcolony until the formation of a monoclonal plant cell line.

A piston for an internal combustion engine may include a piston head and a piston shaft. The piston shaft may have two shaft walls, one arranged on a pressure side and the other arranged on a counter-pressure side. Two box walls may have pin bosses and connect the shaft walls. Each of the box walls may have a first partial wall section and a second partial wall section. The first partial wall section may extend between the pin boss and the shaft wall arranged on the pressure side. The second partial wall section may extend between the pin boss and the shaft wall arranged on the counter-pressure side. A first longitudinal center line of the first partial wall section is may be convergent to a second longitudinal center line of the second partial wall section, wherein the first and second longitudinal center lines—intersect each other outside the piston.

The invention relates to an optical module for a cellular phone having an image sensor comprising a light sensitive upper side for detecting and converting optical signals into electrical signals, an imaging device for imaging the optical signals on the image sensor, and a circuit board comprising an upper side and a lower side electrically and mechanically connected to the image sensor. In order to create a particularly flat optical module, for example for integration into a cellular phone, the invention provides that the circuit board has a recess in which the image sensor is disposed such that a lower side of the image sensor is substantially located at the same height as the lower side of the circuit board.

摘要:
Common oral diseases such as periodontitis and dental caries can be prevented effectively by passive immunization. The present invention provides human single chain Fv (scFv) and diabody antibody fragments based on the binding characteristics of the murine monoclonal antibody Guy's 13. Like the parent antibody, these derivatives bind specifically to SAI/II, the surface adhesin of Streptococcus and the human diabody derivative is capable of aggregating streptococcal cells, making it a useful candidate therapeutic agent for passive immunization against oral diseases.
摘要:
This invention relates to immunoglobulin molecules comprising light chain (VL) chimeric variable domains, heavy chain (VH) chimeric variable domains, e.g., scFv antibodies that are expressed at high levels within a host cell, preferably within particular cellular compartments such as, e.g., cytosol or apoplast. The VL, VH and scFv antibody molecules comprise framework scaffolds of particularly preferred framework regions. This invention also relates to nucleic acid molecules encoding the immunoglobulin molecules of this invention, vectors expressing the immunoglobulin molecules, hosts transformed with the nucleic acid molecules and vectors, and methods of using the immunoglobulin molecules. Also described are immunoglobulin libraries as well as host cells, including transgenic plants, expressing the VL, VH or scFv antibody molecules of this invention.
