Definitions
- the tau protein As described above, the tau protein
- a disadvantage of known diagnostic methods using the previously known diagnostics is that early and complete detection of high-risk patients fails and therefore a diagnosis or therapy is insufficient or even too late.
- Tyrosine Receptor Kinases and SEQ ID No. 129 to SEQ ID No. 179 are to be assigned to the "membrane-bound cytokine receptors". Furthermore, the former are in the enzyme class EC 2.7.10.1
- Receptor kinases or membranous cytokine receptors ". Also included are those analogous amino acid sequences that are due to the exchange of one or more multiple amino acid (s) in these sequences, yet have the desired function of a “tyrosine receptor kinases” or “membrane-bound cytokine receptors”.

- human antibodies e.g., IgG, IgM or IgG and IgM.
- the label enables its detection, e.g.
- detected secondary antibody e.g. with a
- Fluorescence scanner This results in a quantitative or semiquantitative signal for each sample immobilized on the array (potential autoantigen and controls).
