A novel bilirubin antigen capable of functioning as an antigen which does not undergo decomposition in vivo. This antigen has a structure wherein a protein is bound to the methylene group of the outer vinyl group present in the outermost ring of bilirubin through a spacer or to at least one carboxyl group. A monoclonal antibody capable of recognizing the bilirubin antigen can be obtained from hybridoma cells prepared by cell fusion between antibody-yielding cells obtained by immunizing with the bilirubin antigen and tumor cells capable of division and growth in a culture medium. This monoclonal antibody can recognize bilirubins present in vivo without decomposing their structures, and hence it enables direct qualitative and analyses of bilirubins.

L'association d'une peroxydase capable de réduire les peroxydes organiques et d'un anti-oxydant capable de neutraliser l'oxygène singulet permet de prévenir ou traiter les dommages cellulaires provoqués par les radicaux libres induits par les polluants atmosphériques ou par le rayonnement ultra-violet.
On obtient ainsi des compositions cosmétiques ou dermopharmaceutiques permettant de lutter contre le vieillissement accéléré de la peau, et de réduire les risques de cancer cutané photo-induit.
There is described an apparatus for measuring protein characteristics comprising an X-ray fluorescence (XRF) spectrometer comprising a source of polychromatic X-rays, an X-ray detector, a protein, a molecule that has been exposed to and at least weakly binds to the protein, a plurality of X-ray fluorescence signal data obtained by irradiating chemical elements in the protein and molecule with the polychromatic X-rays and a security system for maintaining records for the data from the plurality of X-ray fluorescence signal measurements. There is also described an x-ray microscope for measuring a sample.
