Halo University USP788: Validating your Aura for US Pharmacopeia (USP) Sub-visible Particle Analysis
Subvisible particles (SVP) are a critical quality attribute (CQA) for protein therapeutics that can limit a product’s shelf-life and induce immunogenicity. In this Halo University lecture, we present a pathway to validating the Aura platform for USP sub-visible particle counting. Combining Backgrounded Membrane Imaging (BMI) for total particle analysis with Side Illumination Membrane Imaging (SIMI) for external contaminants, including plastics, glass, and metals; enables the accurate determination of particles to support your USP 788 and 787 compliance requirements. Here, we focus on these techniques to help validate the Aura® platform, providing useful insights into determining the instrument, user, and sampling variability, and key criteria to define reproducibility of results.
Key Learning Objectives:
- Define the key USP criteria for SVP particle analysis
- Differentiation of particle sub-species in complex mixtures using BMI and SIMI, including data filtering using expression analysis
- Approaches to determine the accuracy and reproducibility of counting, sizing and operator performance
