Pair-wise Epitope mapping of monoclonal antibodies

06.07.2004


The graph shows the binding of an RGS-His fusion protein to immobilised antibodies against a tetra-His, a penta-His and an RGS-His epitope. All antibodies recognize the epitope but only the anti-RGS-His antibody shows no dissociation when bound to the RGS-fusion protein after an association time of 450 seconds.


A complete characterization of monoclonal antibodies also includes the determination of epitope specificity for a given set of monoclonal antibodies. Epitope mapping is a powerful tool in analysing the surface topography of an antigen. The binding of an antibody to the antigen defines a specific binding site or epitope which sterically interferes with the binding of another antibody which has the same or a closely located binding site. The specificity of pairs of antibodies can easily be determined by testing the simultaneous binding to the antigen. Dinstinct binding sites can be identified by binding of both antibodies in parallel whereas an identical or closely located binding site prevents binding of the second antibody. BIA technology (Biomolecular Interaction Analysis) is ideally suited to automatically test panels of monoclonal antibodies and define their epitope specificity pattern.

Our antibody service “eitope mapping” includes the generation of working plans for the experimental setup, the performance of the epitope mapping analysis on a Biacore instrument and the complete evaluation of the results documented in a written report with figures. This report provides you with information about the epitope specificity pattern for your set of monoclonal antibodies i.e. which antibodies bind to the same epitope and which can bind simultaneously because they have different binding sites on the antigen. Please enquire for a detailed quote concerning your specific problem.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
