fagyasztóaktárak

Fagyasztóaktárak, meaning "freezer archives" in Hungarian, refers to the practice of storing frozen biological samples for long-term preservation. These archives are crucial for various scientific and medical fields, including genetics, cryobiology, and regenerative medicine. The samples can encompass a wide range, such as sperm, eggs, embryos, stem cells, blood, tissues, and even entire organisms or their genetic material.

The primary purpose of a fagyasztóaktár is to maintain the viability and integrity of biological specimens over extended periods. This is achieved through cryopreservation, a process that involves rapidly cooling the samples to extremely low temperatures, typically below -130°C, using cryoprotective agents to prevent ice crystal formation and cellular damage. Liquid nitrogen is commonly used as the storage medium.

These archives play a vital role in preserving biodiversity, aiding in fertility treatments, facilitating research into diseases, and potentially enabling future therapeutic applications. They serve as a safeguard against extinction for endangered species and provide a valuable resource for genetic studies. The establishment and maintenance of fagyasztóaktárak require specialized equipment, stringent protocols, and constant monitoring to ensure the long-term success of the stored samples.
