Manufacturing antibodies
Date:3/18/2010

EUREKA project E! 3424 RECAN has developed a range of unique and highly specific monoclonal and polyclonal antibodies the proteins produced in the blood which counteract bacteria, viruses or cancerous cells. This was achieved by first producing a number of recombinant proteins which are important components of cellular signalling pathways. These proteins themselves have direct uses in immunisation and experimental studies. A further key advance is the incorporation of novel fluorochrome dyes with specific monoclonal antibodies, which can then be used in diagnosis of leukaemia and rheumatic diseases; also in oncology and haematology research.

The human immune system protects the body from disease by identifying and destroying the agents of disease bacteria, viruses and also its own cells if they become transformed into a potentially cancerous tumour. The immune system depends on the activity of antibodies, which are naturally produced within its white blood cells. The structure of antibodies has many millions of variations; each capable of recognising and marking a specific antigen, for example from a specific bacterium, so that the bacterium of that strain can be identified and destroyed by other types of white blood cells. If a molecule from a specific bacterium binds to a receptor protein on the surface of the white blood cell, the protein, which is an important component of the signalling pathway, triggers a response within the cell. In addition, antibodies can serve as an extremely useful research and diagnostic tool, as they can bind with great specificity and sensitivity to their target structures and then can be visualised by staining with specific dyes.

The Antibodies fabric

Modern molecular techniques now enable in vitro production of some of the receptor proteins. The RECAN project used recombinant techniques to produce them combining defined DNA sequences with the DNA of bacteria to alter the coding for specifi
