What Is Cell Therapy Manufacturing?
August 30, 2024 • By Mike Barlow
Cell therapy manufacturing involves several complex steps that require specialized training, equipment and strict quality assurance and control measures to ensure the safety, efficacy, and consistency of the final product.
Cell Therapy vs. Gene Therapy: What’s the Difference?
July 12, 2024 • By Mike Barlow
In modern medicine, two powerful technologies—Cell Therapy and Gene Therapy—are reshaping how we treat serious diseases. Both aim to repair or replace what’s malfunctioning inside the body, but they take fundamentally different approaches.
What is A GMP Deviation Investigation?
August 26, 2023 • By Mike Barlow
In GMP pharmaceutical production, including biologics and cell therapy manufacturing, a GMP Deviation Investigation is the structured process used to identify, document, analyze, and resolve any unexpected events or conditions that do not comply with approved procedures, specifications, or regulatory requirements.
Biologics Manufacturing Processing Steps
August 21, 2023 • By Mike Barlow, Paul Van Buskirk
Typical biologics manufacturing involves culturing cells in bioreactors (upstream processing) to produce the target protein, followed by harvesting to separate cells from the product-containing broth. The product is then purified through downstream processing methods like filtration and chromatography. Finally, it's formulated with stabilizers, filled into sterile containers, and undergoes quality testing before release.
What is Tangential Flow Filtration?
July 27, 2023 • By Mike Barlow
Tangential Flow Filtration (TFF), also known as Crossflow Filtration, is a widely used separation technique in biologics manufacturing for processes such as concentration, diafiltration, and buffer exchange of biomolecules like proteins, antibodies, and vaccines.
What are Biologics?
May 18, 2023 • By Mike Barlow
In biotechnology, biologics are therapeutic products made from living cells or organisms. Unlike chemically synthesized drugs, biologics are usually large, complex molecules such as proteins, cells, or genetic material.
