In the realm of biotechnology, the ability to preserve cells effectively is crucial for various applications, including regenerative medicine, biobanking, and cellular therapies. However, one of the most significant challenges in the field of cryopreservation has been the control of ice formation during the freezing process. A breakthrough has emerged from HOHCells, a Maryland-based biotechnology device company, which has introduced FreezOpt™, a patented cryovial insert designed to address this long-standing issue.
Understanding the Cryopreservation Process
Cryopreservation is a process used to preserve cells, tissues, or any biological constructs by cooling them to sub-zero temperatures. This process halts cellular metabolism and significantly slows down biological activity, allowing for the long-term storage of cells. However, the formation of ice during freezing can cause significant damage to cells, leading to reduced viability and functionality upon thawing.
Challenges of Ice Formation
The primary challenge in cryopreservation lies in controlling the initiation of ice formation, known as ice nucleation. When ice forms within or around cells, it can disrupt cellular structures, leading to cell death. Traditional cryopreservation methods often result in uncontrolled ice formation, which has historically limited the effectiveness of this technique.
Introducing FreezOpt™
FreezOpt™ represents a significant advancement in the field by providing researchers with a simple and effective method to introduce control into the cryopreservation process. According to Greg Merril, CEO of HOHCells, the technology allows researchers to enhance their existing cryopreservation protocols without the need for new equipment or extensive procedure alterations. This ease of use is likely to facilitate widespread adoption in laboratories.
Technology Development
The underlying technology for FreezOpt™ emerged from academic research led by Dr. He, who investigated the effects of ice nucleation on cellular survival during freezing. This research has been crucial in understanding how to manipulate the freezing process to achieve better outcomes for cell viability. The intellectual property surrounding this innovation is protected by both issued and pending patents, ensuring that HOHCells can maintain a competitive edge in the market.
Product Features and Availability
FreezOpt™ is currently available as a research-use-only product, packaged in sets of 96 units. The inserts are designed to be compatible with standard cryovials and controlled-rate freezing workflows, making them accessible for a wide range of biological research applications. The product is manufactured in Maryland at Mtech Ventures, located on the University of Maryland, College Park campus, ensuring a local production source for researchers in the area.
