Abstract
Abstract In an arrangement for carrying out a radioimmunological method of determining both antigens and antibodies by examining samples of human body liquids by forming an antigen/antibody-complex with a radioactively labelled antibody, a micro-titer-plate is provided with recesses for accommodating a solution of said radioactively labelled antibody and to the sample to be examined. Carriers, in the form of elongated elements secured to a holding band, are loaded with unlabelled antigen and are contacted with the sample by being inserted in the recesses of the micro-titer-plate. The carrier is washed, and the radioactivity of the carrier is measured.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
In an arrangement for carrying out a radioimmunological method of determining antigens or antibodies of the type including a micro-titer-plate having recesses for accommodation of the samples to be examined and solid carriers loadable with a complex former, the improvement which is characterized in that the solid carriers are elongated plate-like elements and that a holding band is provided to which said elongated plate-like elements are secured, a neck piece of smaller cross section than the elongated elements is provided between the holding band and each elongated element to form pre-determined breaking points, the elongated plate-like elements are insertable in the recesses of the micro-titer-plate.
Claim 2
Dependent Claim
