Because they are able to recognize a particular cell marker — a protein — antibodies are generally used to identify abnormal cells in the body. As such, they play a key role in diagnosis, treatment and basic research.
At the Institut Curie, CNRS research scientists have recently prepared a new type of antibody which for the first time combines several crucial features: it can be produced in a few days, it can be expressed directly in cells, and it is, moreover, sensitive to the shape of proteins. The latter property is particularly important as the activity of proteins depends on their shape. Thus certain cancers or illnesses such as Creutzfeldt-Jakob disease are due to a protein that has assumed an abnormal shape.
This study, which constitutes a technological advance both for basic research and diagnosis, is published in the 9 May 2003 issue of Science.
All stages in the life of a cell are controlled by the activity of proteins. Proteins enable cells to produce energy, to reproduce and to interact with their environment. All these processes must be closely monitored to avoid pathological dysfunction.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
