New Tools and Opportunities in Subvisible Particle Analysis

Characterization of subvisible particles in protein therapeutics has become an increasingly important means to ensure the development of safe, stable, and effective medicines.  Many analytical techniques are available to identify and prevent not only protein aggregation, but to fulfill regulatory requirements. The purpose of this study by Danny Chou, President and Founder of Compassion BioSolution, LLC is to compare different techniques and their ability to identify subvisible particles and what relationship exists between the number of particles and different stress conditions imposed upon the protein drug products.

Flow Imaging Microscopy has been widely implemented for the analysis of particles ranging in size from 1-10µm. Yet, in recent years the FDA has highlighted the need for better analytical tools to fully understand how different stress conditions can impact the stability of the formulation. While light obscuration and membrane microscopy have been the primary methods to conduct USP testing for particles between 10µm - 25µm, regulators are now moving towards expecting orthogonal analytical methods to characterize and provide quantitative data on particles in the 2µm - 10µm range as well.

FlowCam Nano offers the ability to image and analyze particles ranging from 30µm down to as small as 300 nm.

Flow Imaging Microscopy (FIM) Coupled with Convolutional Neural Networks (CNN) Demonstrates Reliable Method to Characterize and Identify Impurities in Cell Based Medicinal Products (CBMPs)

Cell-based medicinal products (CBMPs) are gaining importance as therapeutic treatments for many life-threatening diseases. This study was designed to develop a method to characterize CBMPs using flow imaging microscopy (FIM) for the detection, quantification, and characterization of subvisible particulate impurities.  Recently, FIM has been applied to study cell viability and confluency in cell culture as well as quality of CBMPs. Comprehensive particle characterization can be limited when using the morphological parameters derived from the embedded software due to the complexity of CBMPs, which may consist of multiple particulate populations of highly heterogeneous morphologies.

Boston University Students use FlowCam to Analyze Oyster Habitats from Narragansett Bay, Rhode Island

Nick Ray (PhD Candidate) and Gretchen McCarthy (Senior) from the Boston University Marine Program (BUMP) came to visit our FlowCam lab in Scarborough this week. Nick Ray had used a FlowCam in 2016 in Dr. Robinson Fulweiler's lab when he was a recipient of our Student Equipment Grant. Gretchen has worked in this lab since she was a freshman. She's planning to begin graduate school next year and will focus her studies on fisheries and aquaculture.

FlowCam for Characterization of Column Packing Material

High-performance liquid chromatographyis a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps that pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column.
