RNA preservation of Antarctic marine invertebrates
Fifteen species of marine invertebrate commonly occurring in the near-shore environment of Rothera base, Antarctica, were used to test tissue sample storage protocols with regard to preservation of RNA integrity. After animal collection, the tissues were either immediately extracted for RNA or store...
