A METHOD FOR THE COLLECTION OF ANTIBODIES AND THE DETECTION OF A SPECIFIC ANTIBODY SPECIES IN A FLUID SAMPLE AND A DEVICE FOR CARRYING OUT SAID METHOD AS WELL AS A KIT COMPRISING SAID DEVICE

摘要

The invention relates to a method for collecting antibodies and detecting the presence of a specific antibody species in a fluid sample. The fluid sample is contacted with a solid phase matrix comprising a porous membrane and latex particles bound by means of a recombinant protein A or G, which produces an aspecific binding of antibodies from the sample . An antigen, which is specific for the antibody to be detected, is then contacted with the matrix and forms a detectable complex. The invention also relates to a device and a kit for carrying out immuno-diagnostic analyzes.
