The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Vortex Counter-Current Chromatography (CCC) System
Description of Invention: Available for licensing and commercial development is a vortex counter-current chromatography system. The system has a rotary frame engaged to a vortex separation column for rotation in one direction through a vortex separation shaft engaged to a pulley system. The rotary frame is engaged to a central shaft that rotates the rotary frame in a direction opposite that of the vortex separation column such that planetary motion is imparted to the vortex separation column. The vortex separation column may be configured to receive a solvent system separable between two immiscible liquid phases introduced into the vortex separation column. A pulley system is operatively engaged to the separation column shaft and the central shaft for rotating the separation column shaft and the cortex separation column in a synchronous rotational direction opposite to the rotational direction of the rotary frame for imparting a type-I planetary motion to the vortex separation column. A counter-weight column is engaged at a symmetrical position opposite the vortex separation column along the rotary frame, wherein the two immiscible liquid phases undergo a vortex motion during rotation of the vortex separation column such that mixing of the two immiscible liquid phases takes place with a plane perpendicular to an axis of the vortex separation column.
Compared with conventional CCC systems, the vortex system has much higher partition efficiency in terms of height equivalent to a theoretical plate (only 2 cm compared with 20 cm that is required for the conventional system). The vortex system also provides an advantage of low column pressure which facilitates application of a large industrial-scale separation without a risk of leakage of solvent and column damage caused by high pressure.

Superresolution Microscopy via Azicon Beam Polarization Devices
Description of Invention: The technology offered for licensing pertains to novel polarizers that produce tangentially and radially polarized beams. The polarizers and polarizing beam splitter of the technology include one or more pairs of axicons (also known as conical lenses) that are configured to separate an input beam into a radially polarized component and a tangentially (or azimuthally) polarized component. A second axicon pair can be positioned to recombine the tangentially polarized component so as to provide a more uniform beam intensity. The radial polarized component can be reflected or otherwise directed so that one or both the radial and tangential components are available for use.
The disclosed methods and apparatus of the technology can be used to provide radially or tangentially polarized beams (or both) to many applications. In particular, the technology can be effectively utilized in applications such as:
- Multi-photon microscopy.
- Ultrafine imaging in conjunction with the use of fluorophores.
Advantages: The technology provides higher optical resolution for certain applications as compared with currently used methodologies.
Development Status: The invention is fully developed.

Mucosal Cytotoxic T Lymphocyte Responses
Description of Invention: The invention offered for licensing provides methods and compositions for induction of an antigen-specific, mucosal cytotoxic T lymphocyte (CTL) response useful in preventing and treating infections with pathogens that gain entry via a mucosal surface. The methods of the invention involve administering either a soluble antigen itself, or a polynucleotide encoding the Start Printed Page 54347soluble antigen, to a mucosal surface. The soluble antigens can be full length, naturally occurring polypeptides or fragments (i.e. peptides) derived from them. The soluble antigen is administered with an adjuvant at the mucosal site or without an adjuvant. Adjuvants can be, for example, Cholera toxin (CT), mutant CT (MCT), E. coli heat labile enterotoxin (LT) and others. Cytokines like IL-12 or IFNγ can also be administered to enhance the immunoreactivity. Mucosal routes of administration include intrarectal (IR), intranasal (IN), intragastric (IG), intravaginal (IVG) or intratratracheal (IT). Soluble antigens can be derived from pathogenic viruses (e.g. HIV, influenza, or hepatitis virus), bacteria (e.g. Listeria monocytogenes), or prozoans. Furthermore, the soluble antigen can be tumor-associated antigen for cancer applications.
The utility of the technology has been extensively demonstrated when applied to HIV. Details about the HIV studies are provided in the eight (8) publications cited below.
- Immunization to treat infectious diseases.
- Possible applications in cancer therapy.
Development Status: Proof of concept has been demonstrated, in particular as related to HIV.
