Genetic Resources Collection
The Genetic Resources Collection is a valuable resource at the Museum of Texas Tech University, providing a method for archiving tissues and their DNA for future research in areas such as genomics, systematics, epidemiology, environmental toxicology, and more.
The Museum of Texas Tech University's Genetic Resources Collection is a biological archive of more than 350,000 genetic samples. These samples were taken from >98,000 individuals of predominantly mammals, but also some birds, reptiles, amphibians, fish and invertebrates. The collection is world-wide in scope with especially strong mammalian holdings from the southwestern United States, Mexico, Central and South America, the Ukraine, and Malaysia. The majority of the samples are frozen, but the collection also contains samples in ethanol, lysis buffer, and DNA.
In 2015, Dr. Robert D. Bradley (Director of the NSRL) and Dr. Robert J. Baker (Former Director of the NSRL, now retired) submitted a proposal to the Collections in Support of Biological Research program of the National Science Foundation (NSF) to transfer the frozen tissues of the GRC from mechanical -80°C freezers to vapor-phase liquid nitrogen freezers in order to ensure the collection’s long-term preservation and availability for scientific research. That proposal was fully funded by NSF (see Abstract at http://www.nsf.gov/awardsearch/showAward?AWD_ID=1451925&HistoricalAwards=false.)
Late in 2015, the GRC facility was fully renovated to accommodate the LN system and to upgrade the overall facility. In January 2016, five Taylor-WhartonTM LABS freezers, supplied with liquid nitrogen via an exterior bulk tank and vacuum-jacketed piping, were installed and the process of transferring samples to the LN freezers was initiated.
