## Summary

Agilent Technologies, based in Santa Clara and listed as A, makes the Dako PD-L1 IHC 22C3 and 28-8 companion diagnostics and the Omnis staining platform. Its pathology reagents and instruments sit alongside mass spectrometry and genomics tools, and its PD-L1 assays are tied to the pembrolizumab and nivolumab labels; OnCo also links it to HER2 IHC and ISH companion assays and to Resolution ctDx FIRST. It connects to reference laboratories, companion diagnostics, histopathology and immunohistochemistry and IHC autostainers. Whether the multiplicity of PD-L1 assays can be harmonised, or whether each drug keeps its own test, is the open question its products embody. PD-L1 IHC 22C3 pharmDx has its own page.
