Moving PAT from Concept to Reality
On-line sensors are connected to process side streams and perform periodic automatic sampling, returning fluid back to the process streams after analysis is complete. At-line—or off-line—analyses invo…

Emerging Therapies Test Existing Bioanalytical Methods
qPCR is used to quantify a viral genome in serum, tissue, or body fluids for the purpose of pharmacokinetics (PK), biodistribution, or vector shedding evaluations (3,4,6). It is also used to measure t…

Ensuring Viral Safety of Viral Vaccines and Vectors
Limitation of this method is the flow rate of the fluid, which needs to be modulated for optimal results (21).
Gamma irradiation—ionizing radiation from a radioactive Cobalt 60 source—breaks bo…

Development of Purification for Challenging Fc-Fusion Proteins
In most two-column downstream processing platforms, the first column is Protein A (ProA), which binds the target mAb directly from the harvested cell culture fluid. A low pH buffer is routinely used t…

Impact of Media Components on CQAs of Monoclonal Antibodies
While natural media consists solely of naturally occurring biological fluids and has been proven to be quite useful and convenient for a wide range of animal cell cultures, a key disadvantage is the p…

Hybrid Bioprocessing: A Q&A with Andrew Sinclair
In my view, it's where within the manufacturing process, there are a combination of single-use (SU) materials and re-usable materials in contact with the process and associated fluids. This often refe…

Downstream Processing for Cell-Based Therapies
Acoustic filtration uses standing waves to capture, separate, and concentrate particles in a fluid without having a physical barrier (membrane or filter) like traditional filtration systems. It is, th…
