Delivering gene therapy using viral vectors is the preferred way to treat disease at the genetic level.
Adenoviruses and adeno-associated viruses (AAVs) target a wide range of host cells and achieve high transfection rates without integrating themselves into the genome.
While these delivery methods are successful, harvesting them from cells presents many challenges for medical manufacturers, who use them in both oncology treatments and vaccines.
The traditional freeze-thaw method has been used for years. While successful at harvesting viruses, it is costly in time, labor, and product losses through contamination, ultimately producing inconsistent results.
Most importantly, the freeze-thaw method is incredibly difficult to scale up to production level, meaning it is difficult to deliver adenoviruses and AAVs on a large scale.
The critical challenges for vaccine manufacturers are:
Microfluidics™ offer an accessible alternative to the freeze-thaw method through the robust, efficient, and fully scalable Microfluidizer® technology.
Microfluidizer® processors are high shear homogenizers that perform cell disruption more efficiently than other methods.
The fixed-geometry Interaction Chamber™, part of the unique Microfluidizer® processor design, is the key to this success.
Inside the Interaction Chamber™, material is subject to a uniform application of shear and pressure, breaking cells gently yet efficiently. When compared with the freeze-thaw method, the Microfluidizer® processor ruptures cells in fewer passes, taking a fraction of the time needed.
Whether developing an R&D batch of a few milliliters, or production quantities of several liters, the processing quality is the same. The Interaction Chambers™ expose every microliter of material to the same conditions, leading to minimal product wastage.
Most importantly, the capacity of our processors is directly scalable, simply by increasing the number of micro-channels inside the Interaction Chambers™ on the processor.
Microfluidizer® technology does more than just improve your product yield.
Our equipment is designed to fit into, compliment, and enhance your existing processes, while also providing the flexibility to scale up production in the future.
Here are some of the benefits you’ll see after adopting our industry-leading technology:
