The Human Tissue Resource Network Biorepository is currently comprised of three 190 degree Celsius liquid nitrogen freezers, 30 -80 degree Celsius freezers, 14 -20 degree Celsius freezers and 24 four degree Celsius refrigerators. Vacuum sealers preserve Formalin-fixed paraffin-embedded (FFPE) and unstained slides best for long term storage and utility because DNA, RNA and proteins are affected (diminished or structurally difficult to label in testing) when oxidation and water loss occur.
Rees Scientific Equipment Monitoring System
The Rees system secures the integrity and quality of samples stored in both the primary and secondary sites. Freezer and refrigerator temperature units are automatically monitored 24/7 by electronic wireless probes installed in each unit. This system is designed to provide the ultimate high-security environmental monitoring. The biorepository storage devices feature automatic paging that notifies on-call staff in case of an emergency. The system uses the wireless eCentron technology and also monitors the remote off-site backup biorepository site. The biorepository features an automatic backup electric powered generator and a staff emergency response team that responds to any unit malfunctions. Unit maintenance checks are conducted routinely to ensure optimal performance. A secondary electronic backup monitoring system is under consideration at this time.
