- Twelve research groups participated in the ISOBM TD-3 Workshop in which the reactivity and specificity of 83 antibodies against prostate-specific antigen (PSA) were investigated. Using a variety of techniques including cross-inhibition assays, Western blotting, BIAcore, immunoradiometric assays and immunohistochemistry, the antibodies were categorized into six major groups which formed the basis for mapping onto two- and three-dimensional (2-D and 3-D) models of PSA. The overall findings of the TD-3 Workshop are summarized in this report. In agreement with all participating groups, three main antigenic domains were identified: free PSA-specific epitopes located in or close to amino acids 86-91; discontinuous epitopes specific for PSA without human kallikrein (hK2) cross-reactivity located at or close to amino acids 158-163; and continuous or linear epitopes shared between PSA and hK2 located close to amino acids 3-11. In addition, several minor and partly overlapping domains were also identified. Clearly, the characterization of antibodies from this workshop and the location of their epitopes on the 3-D model of PSA illustrate the importance of selecting appropriate antibody pairs for use in immunoassays. It is hoped that these findings and the epitope nomenclature described in this TD-3 Workshop are used as a standard for future evaluation of anti-PSA antibodies.

Journal article (peer-reviewed)abstract
- Using a panel of human-rodent somatic cell hybrids, we have previously mapped the gene (HPD, previously called PPD) encoding 4-hydroxyphenylpyruvate dioxygenase to the distal half of the long arm of human chromosome 12, region q14-->qter. To obtain a genomic probe useful for fluorescence in situ hybridization (FISH) analysis we screened a human leukocyte genomic library and isolated a 13.4-kb phage clone, which by restriction fragment and sequence analyses was shown to contain exons 1-10 of HPD and approximately 2-kb upstream sequences. We now report the subregional localization of HPD to 12q24-->qter based on two color FISH analysis employing this clone.
