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.
This technology provides improved processes for production and purification of nucleic acid-containing compositions, such as non-naturally occurring viruses, for example, recombinant polioviruses that can be employed as oncolytic agents. Some of the improved processes relate to improved processes for producing viral DNA template.
The technology is directed to the use of single-stranded RNA overhangs or toeholds of varying lengths (< 12 nucleotides) contained in nucleic acid-based nanoparticles which trigger the association of these nanoparticles and activates multiple functionalities such as gene silencing and/or cell-specific targeting. The use of RNA toeholds is superior to that of DNA toeholds in that it allows for smaller nanoparticles (fewer nucleotides for the toeholds) resulting in greater chemical stability, less immunogenic and higher yield of production. The National Cancer Institute (NCI) seeks licensing and/or co-development research collaborations for use of RNA overhangs or toeholds in nucleic acid nanoparticles.
Researchers at the National Cancer Institute (NCI) seek licensing for an improved cell line called Tni-FNL which is capable of high level expression of heterologous proteins using baculovirus expression systems.
The National Cancer Institute seeks parties interested in collaborative research to co-develop or license methods of treating disorders related to polyomavirus, as well as vaccines for patients undergoing immunosuppressive treatment such as multiple sclerosis, rheumatoid arthritis, B cell cancers, and Crohn’s disease.
