Procedure for determining the score of an antibody in relation to a mapping of interest.

<p>(A) Initially, the protein expression levels and the expression difference (<i>ED</i>) between cancer tissue and normal tissue for all antibodies covering all mappings are calculated. (B) The significance of the target <i>ED</i> with respect to the mapping of interest is determined by a cumulative z distribution. (C) The specificity of the target <i>ED</i> with respect to the mapping of interest is determined by another cumulative z distribution. (D) The final score of the antibody with respect to the mapping of interest is determined on the basis of its protein expression level in cancer tissue and the significance and specificity of its <i>ED</i>.
