Energy Efficient Biological Sample Storage
Why do we need Biological Sample Storage?
Biological sample storage is essential for several industries including pharmaceuticals, healthcare, research and forensics. Correct sample storage ensures the viability of samples by slowing or stopping degradation of biological materials so that they can be used or investigated for some time after collection, without compromising the sample integrity.
How to Store Biological Samples
Ultra-low temperature (ULT) freezers provide the necessary conditions for preserving biological specimens.
Storing biospecimens at -80 °C preserves the sample by slowing or stopping natural functions. The optimal storage conditions depend on the type of tissue sample, for example proteins can be stored for only six years at -80 °C but adrenal tissue can be stored for up to 27 years.
To prepare samples for ULT storage, they must be frozen, either in a blast freezer or with liquid nitrogen. When the sample is ready to be used, it should be warmed quickly, for example in a water bath.
It is important to note that the number of freeze-thaw cycles a sample undergoes can affect its quality. If a number of experiments will be carried out on a sample at different times, it may be pertinent to aliquot the sample before freezing.
Biological Sample Storage: Industry Applications
There are many industries that make use of ULT Freezers for biological sample storage. Outlined below are some examples of industries that use ULT freezers for preserving biological specimens.
Biobanks: Biobanks, or biorepositories, are used for biological sample storage and preserving biological specimens. Biospecimens are collected and stored for future research. The types of samples stored include human tissues for DNA analysis. These samples can be used for future research to investigate how DNA can affect human health. ULT freezers provide a suitable option for medium-long term DNA preservation so that samples can be stored and studied over time.
Pharmaceutical research: Biological sample storage for healthcare research has become very important. Long term storage of various human samples is key for investigating and researching diseases and treatments, such as personalised medicine based on a person’s genetics.
In recent years, ULT freezers have also become popular for vaccine storage. Storage of pharmaceuticals at such low temperatures ensure the active ingredients remain potent by slowing their degradation. ULT Freezers can be used for the storage of other medicines to increase their lifespan compared to storage at higher temperatures.
Hospitals: ULT freezers are used for the storage of biological substances such as blood plasma, stem cells and bone marrow. These can be used for treatment of patients, diagnosis of patients or for investigating diseases and further research.
Forensics: Biological evidence collection and preservation is very important for criminal investigations. Evidence collected at crime scenes will sometimes be stored for a long time before a trial is held. Evidence that must be kept for possible future investigations must be stored so that degradation is kept to a minimum to ensure the most accurate analysis can be carried out at any time.
