SC14: USP Standards to Support Quality of Potency Measurements

THURSDAY, MAY 7 | DINNER, 5:45 – 8:15 PM


USP’s innovative public standards for bioassays have supported potency measurements for decades. Standards range from best practices for development, validation, and analysis of bioassays in general to more specific issues such as Fc receptor assay function or new in vitro assays to replace in vivo assays. This course will delve into the current state of documentary standards as well as new biologics reference standards that support product quality and consistency over time.


  • History of USP Standards
  • What is a potency measure?
  • USP bioassay chapters and revision status of chapters <1032> and <1033>
  • New General Chapter <1108> to support Fc receptor assays
  • New biologics Reference Standards that are fit for purpose
  • Use of standards to support potency measurements, trending, and stability testing
