A high-throughput tissue profiling platform was set up to allow comprehensive immunohistochemistry-based analysis of protein expression patterns in normal human tissues, cancer tissue, and cell lines. Altogether, more than 700 individual microarray samples were immunohistochemically stained for each antibody. A web-based annotation system was developed to allow for evaluation and scoring of immunohistochemical staining patterns in tissues, and the manual analysis was performed by pathologists in Sweden and India. Protocols were standardized to enable a global, immunohistochemistry-based protein profiling of unprecedented magnitude.
