Leukopaks are critical for treating certain diseases. When a delivery of leukopaks arrives, you'll want to make sure that you take special steps when preserving it. How you preserve it will be based on the state that the leukopak arrives in and how long before you intend to use it.
Fresh Leukopaks Vs. Cryopreserved Lukopaks
When you receive a fresh leukopak, you'll want to use it immediately. If you will not be able to use a leukopak immediately, consider purchasing a pack that are cryopreserved. This is the process by which materials are cooled to a very low temperature so that enzymatic or chemical activities that would have caused damage to the leukopak are otherwise prevented.
The primary goal is to reach a lower temperature without causing damage to the leukopak, which would result from the formation of ice crystals. Anything that would cause damage to the leukopak is stopped so that the leukopak may be used to treat various diseases.
Storing a Leukopak
Prepare the leukopak for long-term storage in a liquid nitrogen vapor phase or thaw it to use it. It should not be stored in a liquid nitrogen phase only, unless it will be stored for less than two weeks.
Why Leukopaks Must Be Kept at a Low Temperature
Any living organic material degrades as a result of aging and also suffers changes as a result of the environment, which can lead to the loss of a product. For that reason, measures must always be taken to store leukopaks properly in a manner that will prevent degredation.
The Benefits of Cryogenic Freezing
Cryogenic freezers use liquid nitrogen to preserve materials in a manner that is efficient and cost-effective. The cells are placed in a state of suspended animation and can theoretically be preserved for centuries, though this hasn't been tested. All cell activity ends, so the leukopak should theoretically not degrade. However, for leukopaks, the goal is generally not to keep them for so long, but to instead put them to use.
Vapor Phase Vs. Liquid Freezing
Vapor phase freezers are ideal because they allow for quick and easy access to your leukopaks. The only time that the liquid version is recommended is in the unlikely scenario that you'll plan on storing your leukopaks for an extended period. Trying to retrieve a product that is kept at -196 degrees Fahrenheit can be potentially dangerous to those who are handling the materials.
