Particle Characterization Ensures Quality Therapeutic

February 26, 2015
Angelica Olcott, Product Manager, MFI, ProteinSimple

Sub-visible particles lie in wait during product development, ready to impair product stability when you least expect it. But how can you catch them before they act? In this webinar, Angelica Olcott will show how MFI can help you quickly screen for sub-visible particles during development and manufacturing. Sensitive image-based detection can quantitate silicone oil and translucent protein aggregates that older pharmacopeial methods, like LO, can miss. So if you're only using LO for USP <787>, you'll miss out on critical product quality and safety information.

Discussion Topics:

  • Quickly screen during development and manufacturing for sub-visible particles such as protein aggregates and silicone oil
  • Use particle classification to evaluate product quality and stability


Simple Approaches to Monitoring Biopharmaceutical Purification with MFI

December 9, 2014
Aaron Noyes, Scientist, Purification Process Development, Pfizer
Angelica Olcott, Product Manager, MFI, ProteinSimple

Sub-visible particle analysis using micro-flow imaging is critical to monitor biopharmaceutical product quality and safety. Compared to older techniques which only provide particle size and count and can undercount, MFI also provides particle morphology. As a result, MFI can resolve complex particle types such as protein aggregates from silicone oil and other contaminants.

During purification of biologicals, complex particle environments are common. In this webinar, Aaron Noyes, Scientist at Pfizer, will show how MFI presents a fresh approach for characterizing biopharmaceutical production processes of mAbs and vaccines. Case studies focused on flocculation, precipitation, and filtration will demonstrate how measuring particle size, count and morphology can enhance process understanding, improve productivity, and ultimately, increase the robustness, of biopharmaceutical production processes.

Angelica Olcott, Product Manager, MFI, ProteinSimple

Discussion Topics

  • Effective detection of sub-visible protein aggregates
  • Using MFI as a quality control method in a GMP environment
  • Particle classification of protein aggregates and silicone oil


Characterizing sub-visible particles, including protein aggregates, is now required to ensure both quality and stability of protein therapeutics. Micro-Flow Imaging is ideal for particle characterization because it uses dynamic imaging for direct particle detection. This technology enables rapid quantification of particle size and shape for tens of thousands of particles per sample and the sensitivity to detect translucent protein particles. As a result, MFI analysis provides the ability to rapidly classify protein aggregates and other particle types such as silicone oil and extrinsic contaminants. In this webinar, Daniel Weinbuch will present how to use filter analysis on MFI to accurately classify particles, such as silicone oil and protein, based on shape and image intensity.

Go with the Flow: Easy Particle Characterization with Micro-Flow Imaging

February 27, 2014
Jessica Dermody, Ph.D., Field Application Scientist, ProteinSimple
Chris Heger, Ph.D., Field Application Scientist, ProteinSimple

Characterization of protein aggregates and other sub-visible particles is essential for monitoring changes in product quality and safety throughout biopharmaceutical development. A unique challenge for particle characterization is the simultaneous presence of protein aggregates and other particle types such as silicone oil micro-droplets, air bubbles, and extrinsic contaminants protein formulations. Traditional techniques providing only size and concentration information cannot distinguish these groups from each other. More comprehensive technologies must therefore be utilized to detect and classify particles into sub-groups based on their unique morphology and particle characteristics.

ProteinSimple's Micro-Flow Imaging (MFI) is ideal for characterization of biopharmaceuticals because it not only measures particle size and count, but also provides quantitative images that allow scientists to sensitively discriminate particle types based on their shape characteristics. In this webinar we will demonstrate how image information provided by MFI can be used to quickly and easily design morphologic filters for routine analysis. We will also review a variety of case studies which describe how to customize and test these filters for accurate particle classification in protein formulations.

Robust instrument validation in an industrial or biotechnology setting can often be complex and time-consuming to create on its own. To aid in this process, ProteinSimple offers 21 CFR Part 11-enabling software with our instrumentation (MFI View System Software), as well as instrument qualification services. IQOQ (Instrument Qualification/Operational Qualification) confirms instrument performance according to manufacturing specifications, and can be implemented following system installation. IQOQ in a QC environment provides a number of benefits for verification of instrument accuracy and proper maintenance, and can form a part of a customer's overall system validation. In this tech talk, Craig Haupt, our Director of Field Service Engineering, describes the format of IQOQ for MFI systems and describes specific examples of MVSS software designed for 21 CFR Part 11. Industry experts are invited to join the Q&A session which follows and provide their perspective.
