Cryopreservation is the process in which biological constructs, cells, organelles, or tissues are preserved by storing and transporting them under low temperatures. This process has become very popular in recent years. Viable tissues and stem cells are used in basic research and in medical applications.
Temperature control equipment and cryoprotective agents are used to store, preserve, and transport biological specimens to the lab or other research centers. You can contact a reliable transport company when moving your biospecimens by visiting https://www.cryosend.com/.
Cryopreservation Procedure
Cryopreservation involves preserving the structurally intact living tissues and cells for many hours by exposing them to very low temperatures. This process is grouped into four types namely slow freezing, vitrification, subzero nonfreezing storage and preservation of sample in the final dry stage. The processes followed in cryopreservation include mixing of tissues/cells with CPAs, cooling of the tissues/cells to a very low temperature, warming of cells, and finally separation of CPAs from the tissues after thawing.
CPA is a fluid used to improve the samples’ viability. The CPA used should have low toxicity and biologically acceptable. It’s optimizing the concentrations of CPA is the best way of increasing the survival rates of tissues/cells, cooling rate, warming rate, and the sample volume. Its concentration depends on the context of tissues and the type of the cell used.
Why Should Hire a Cryopreservation Transport Company?
Many companies offer cryogenic transportation services. Understanding the chemical and physical properties that occur during this process can help you in choosing a reliable transport company when taking your samples to the lab.
Storing and transporting the samples in a frozen vessel is an effective way of reducing biological activities. This is the main reason why you find clinicians and researchers relying on improvised methods for transporting and handling the frozen biospecimens such as placing them on liquid nitrogen or dry ice. You should hire reliable companies that can safely transport and handle your cryogenic specimens.
