A defined coating of fusion proteins from a constant fusion partner and a variable antigenic part in diagnostic test systems

摘要

The invention relates to solid support materials, e.g. microtitre plates, beads or microbeads, magnetic particles, films, filter papers and the like, which are coated with antibodies against recombinant fusion proteins, and to processes for the reproducible and defined coating of these surfaces with such recombinant fusion proteins. The recombinant fusion proteins contain a constant fusion partner and a variable antigen portion which constitutes the specificity of the test system. The abovementioned antibodies are directed against the constant fusion partner, that is to say the part of each fusion protein which is intrinsically not of analytical interest and pure.
