New Applications for FlowCam in Biotherapeutic Development

Pictured above, protein aggregates, sucrose particles, and E. coli as

for each particle is shown below their image.

Many new types of biotherapeutic Active Pharmaceutical Ingredients (API) such as viruses, nanomedicines including virus-like particles and lipid nanoparticles, and cell-based medicinal products have recently experienced a significant surge in interest. Like proteins before them, formulations of these APIs contain particles that need to be characterized to ensure product quality and efficacy. Particle characterization technologies like FlowCam thus continue to play a critical role in developing and manufacturing safe biotherapeutics regardless of the API.

Meet FlowCam Nano: Submicron Particle Imaging and Sizing

We’re excited to announce the next-generation FlowCam Nano! The newest member of our FlowCam instrument family detects and images particles between 300 nm and 2 µm—the smallest objects visible by light microscopy.

FlowCam Nano can be used to determine the types of submicron particles present in samples, such as biotherapeutic particles or aggregates, drug delivery vehicles, bacterial cells, and other nanoparticles of interest. If not addressed, many of these smaller particles are prone to agglomeration into larger subvisible and visible particles. FlowCam Nano may be used to identify and mitigate these smaller particles before larger ones will form. Other species like bacterial cells inherently exhibit a size near or below the lower size limit of FlowCam 8000 and will only be detected by FlowCam Nano.

FlowCam with Light Obscuration is Now Available

While analysis with light obscuration is standard, the FDA has long made clear that size data alone, collected with light obscuration, is not adequate to ensure safe and effective drugs. Orthogonal methods such as flow imaging microscopy are necessary to provide validation.

With the FlowCam LO, the first and only light obscuration (LO) instrument with imaging capabilities is now available. This easy-to-use instrument delivers a powerful, all-in-one solution to meet compliance standards while allowing verification with high-resolution images.

Explore our new technology in the video below.

Top FlowCam Studies for the Biopharmaceutical Industry

Flow Imaging Microscopy is currently recommended by the USP as an orthogonal analytical method for biopharmaceuticals. It has yet to be integrated into every drug development and testing laboratory however. Integrating new technologies upstream in the formulation development process continues to be an essential path for improving the safety and efficiency of the drug development. Once new methods and technologies are proven and accepted upstream, it's possible to pave the way for new technologies to be implemented downstream and beyond. 

Hundreds of biopharmaceutical and pharmaceutical companies worldwide are now using the FlowCam to improve the quality, safety and stability of their formulations. Since most teams purchasing an analytical instrument for their lab want to read studies conducted by other scientists, we have gathered a collection of the top influential studies using the FlowCam to demonstrate how they are integrating Flow Imaging Microscopy into their research.
