Abstract | The frozen tissue collection of the University of Central Oklahoma Natural History Museum houses specimens collected and preserved in cryotubes without the use of lysis buffer or ethanol as a preservative. These specimens are frozen at the time of collection (either in liquid nitrogen or a -20C freezer) and ultimately stored at -60C to -80C. Tissues are associated with voucher specimens accessioned into subsections of the museum (e.g., birds, mammals, reptiles and amphibians, invertebrates, etc.). |
