Protein specific index arrays facilitate optimal quality control of reagents, staining protocols, definition of threshold of detection and testing of specificity and sensitivity of reagents. These arrays are therefore useful tools for assay optimization, standardization and quality control. Index arrays consist of 30 to 40 tissue specimens and cores of FFPE cell line pellets, both representing a range of expression levels of the target of interest.
