Abstract: The invention relates to a method for the quantification of the total gluten content of grains in food samples. Areas of application are primarily the food industry, service laboratories and government test laboratories or biotechnology. The invention aims to quickly and cost-effectively determine the total gluten content in foods with just one measurement. We include a method with which, based on the detection of prolamins and glutelins, all potentially coeliac-relevant gluten protein fractions in food samples are quantified as a total corresponding to their mass. The method is based on the joint use of specific prolamin and glutelin antibodies as a combined conjugate according to the invention for the detection of the total gluten content. In addition, the individual antibody conjugates are thinned so that the contribution of the individual antibodies to the total signal strength corresponds to the proportion of the gluten fraction that they each detect.

Abstract: A procedure for the identification of a functional disorder of the pancreas by the use of parts of all iso-enzymes of the pancreas elastase and of synthetic amino-acid sequences as antigens for obtaining specific antibodies, as well as their use in immuno-chemical test procedures.

Abstract: The present invention provides a test medium comprising a test microorganism, an indicator and a metal in ionized form, wherein the valence of said metal is at least 2 and the concentration of said metal is between 0.001 M and 1 M. Furthermore, there is provided a method for the determination of the presence of an antibiotic characterized in that a metal salt is added to said test medium and/or to said sample of fluid. Finally, there is provided a kit suitable for the determination of an antibiotic in a fluid.
