Researchers at the National Cancer Institute (NCI) have developed an engineered storage unit for frozen tissue, that provides a permanent base on which to mount tissue frozen in OCT and an enclosure for storage. The unit provides for chain-of-custody labeling and acts as an insulating container to protect the specimen. Other elements include devices for freezing the tissue to the base, as well as a holder for the base to facilitate cryosectioning. Application of the storage system allows a frozen tissue specimen to be moved between storage and cryosectioning without loss of label, deformation of tissue, or thermal alterations.
Pre-clinical radiotracer biomedical research involves the use of compounds labeled with radioisotopes, including radio-ligand bio-distribution studies, cell binding studies, immune cell labeling techniques, and α-based therapies. Before this Micro-Dose Calibrator, measurement of pre-clinical level dosage for small animal studies was inaccurate and unreliable. This dose calibrator is a prototype ready for customer testing and scale-up. It is designed to accurately measure radioactive doses in the range of 50 nCi (1.8 kBq) to 100 µCi (3.7 MBq) with 99% precision. The NCI seeks co-development or licensing to commercialize it. Alternative uses will be considered.
Surgery specialists from Johns Hopkins University, in collaboration with researchers at the National Cancer Institute (NCI), developed peptide hydrogel compositions and methods to suture blood vessels during microsurgery. The hydrogels particularly benefit surgeons in whole tissue transplant procedures. The NCI seeks co-development research collaborations for further development of this technology.
