Dry shipper with inner canister and shipping case. A dry shipper, or cryoshipper, is a container specifically engineered to transport biological specimens at cryogenic temperatures utilizing the vapor phase of liquid nitrogen. [1] [2]
Biological specimens in an elementary school science lab. A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are ...
A biorepository is a facility that collects, catalogs, and stores samples of biological material for laboratory research. Biorepositories collect and manage specimens from animals, plants, and other living organisms. Biorepositories store many different types of specimens, including samples of blood, urine, tissue, cells, DNA, RNA, and proteins ...
Place one insect identification slip (step #11) in the shipping box and mail specimens to the specialist for identification. Clip (use paper clip) all file copies of species determination cards together and place in pending section at the back of the number file. Place the other cards in the proper place in the number file.
The specimens stored by a biobank and made available to researchers are taken by sampling. Specimen types include blood, urine, skin cells, organ tissue, and other materials. Increasingly, methods for sampling tissue specimens are becoming more targeted, sometimes involving the use of MRI to determine which specific areas of tissue should be ...
Trawls were large metal nets towed behind the ship to collect organisms at different depths of water. [16] Upon the retrieval of a dredge or trawl, Challenger crew would sort, rinse, and store the specimens for examination upon return. The specimens were often preserved in either brine or alcohol.
A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. [1] At low temperatures (typically −80 °C (−112 °F) or −196 °C (−321 °F) using liquid nitrogen ) any cell metabolism which might cause damage to the biological ...
