The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell.
The invention relates to novel lipid-based nanoparticles (liposomes) for use in targeted, on demand and on site drug delivery. The particles include a wall surrounding a cavity, wherein the wall is comprised of:
phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG2000), and
The accurate placement of transplanted tissue at a precise position in the retina is difficult but critical for a successful implementation of an ocular surgical intervention.
Researchers at the National Eye Institute (NEI) have discovered an invention describing a composition and method(s) of using such composition for preserving viability of cells, tissues, or organs at a low temperature (around 4ºC). Current cold storage solutions or methods for cells, tissues, and organs are suboptimal due to irreversible damage to cold-sensitive tissue or organ transplants that need a longer term of storage for facilitating clinical practices.
The culture of mouse embryos ex utero and continuous monitoring and imaging of embryos as they develop have applications in drug testing, genetic studies, and basic research on embryonic development. However, the embryo culture systems currently available for post-implantation embryos include rolling bottle culture systems, which do not permit imaging of the developing embryos and do not support the long-term survival and development of embryos ex utero.
Summary:
The National Eye Institute seeks research co-development partners and/or licensees for an adeno-associated viral gene therapy for Oculocutaneous Albinism type 1A.
WNT1-induced secreted protein-1 (WISP1) is expressed at high levels in osteoblasts and their precursors. WIPS1 plays an important role in various aspects of bone formation. Scientists at the NIH generated Wisp1-deficient (Wisp1-/-) mice. Deletion of Wisp1 resulted in a decrease in bone mineral density, total bone volume, bone thickness, and biomechanical strength.
