Biomarker Lab Capabilities


Flow Cytometry and Cell-based Assays

PPD® Laboratories biomarker lab has access to state-of-the-art instrumentation in both the bioanalytical lab and the central lab. The biomarker lab can accommodate research assays to fully validated assays with CAP/CLIA, GLP and GCLP compliance. The lab also provides training to clinical sites on proper sample processing for complex procedures, such as phospho-flow and activation assays. The biomarker lab has experience with various sample types including whole, frozen and lysed blood, as well as PBMCs. The test menu includes routine cell surface assays and intracellular assays.

Key Instrumentation:

BD FACSCanto™ II flow cytometers

  • Nine flow cytometry systems with multi-parameter analysis capability
  • Three lasers and 10 detectors per system
  • Accurate results for experiments requiring up to 10 parameters

BD FACSCalibur:

  • Two flow cytometry systems with two lasers each

Ligand Binding Assays

The biomarker ligand binding laboratory offers traditional ELISA, electochemiluminescence and microfluidics based ELISA. The lab works in consultation with clients to develop a tiered approach to validation depending on the needs of the program or phase of development of the biomarker.

Our biomarker experts are in close contact with the various lab locations to ensure integration and a smooth transition of assays and technology during development of the biomarker program.

Key Instrumentation:

  • MSD®
  • ELISA
  • ProteinSimple ELLA
  • GYROS
  • Luminex

Immunohistochemistry

Our anatomic pathology lab personnel have more than 60 years of combined experience in anatomic pathology services and research. We continuously add new immunohistochemistry (IHC) and special stains in response to project and client needs.
