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: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
