Sample Collection and Shipping
We provide guidelines for collection, preservation and shipping of high-quality samples for genome sequencing. Collection of cetacean tissues and international shipping may require special permits.
Sample Collection, Shipping Protocols, and Guidelines
These protocols are the current best practices for collection of tissue and blood for the Vertebrate Genomes Laboratory at The Rockefeller University, New York.
Flash-freezing tissue with ethanol and dry ice (when liquid nitrogen is not available)
Preservation of RNA
RNA is important for genome annotation, and RNA from multiple tissues can increase the diversity of expressed genes that can be identified. In addition to flash-frozen tissues for DNA sequencing, samples of various tissues can be stored in RNAlater and then frozen at -80°C. It is important to note that samples stored in RNAlater can only be use for RNA extraction, not ultra-high-quality DNA for genomic sequencing. However, RNA samples do not have to be from the same animal as the tissue used for genomic sequencing. If multiple tissues can be obtained, the order of priority is as follows: (1) brain, (2.) gonads, (3) lungs, (4) liver, (5) muscle, (6) blood, and (7) cells (cultured fibroblasts).
International transport, and the collection, use, and storage of cetacean samples are regulated under CITES (Convention on International Trade of Endangered Species of Wild Fauna and Flora) and the U.S. Marine Mammal Protection Act (MMPA) in the United States. Information on permit requirements and shipping procedures for the Vertebrate Genomes Laboratory are included in the step-by-step guidelines. To arrange shipping, please contact us prior to arranging a shipping date to ensure appropriate permits and procedures are in place.
