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.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
