Multiplexing Homocysteine in Primary Newborn Screening Assays Using Maleimides as Select Derivatization Agents

Homocystinuria (HCU), a group of inherited disorders, causes symptoms ranging from failure to thrive and developmental delays in infants or young children to abnormal blood clots with onset in adults.1 Approximately 1 in 200,000 to 335,000 people have HCU globally.2

Recombinant Vaccines Based on Poxvirus Vectors

The technology offered for licensing is foundational in the area of recombinant DNA vaccines. In the last several years, facilitated through a licensing program of the NIH, the technology has been broadly applied in the development and commercialization of several novel human and veterinary vaccines in the areas of infectious disease as well as cancer therapeutics. The NIH wishes to expand its licensing program of the subject technology in a variety of applications that will benefit public health.

Inhibition of HIV Infection through Chemoprophylaxis Using Emtricitabine and Tenofovir

The invention is directed to prophylactic administration of emtricitabine (FTC) in combination with tenofovir or its prodrug, tenofovir disoproxil fumarate (TDF), to protect against transmission of human immunodeficiency virus (HIV) infection. Also disclosed are other nucleoside reverse transcriptase inhibitors (NRTIs) and nucleotide reverse transcriptase inhibitors (NtRTIs) that, when administered in combination, protect against HIV infection.

Non-Contact Total Emission Detection Methods for Multiphoton Microscopy: Improved Image Fidelity and Biological Sample Analysis

The technology offered for licensing and for further development is in the field of multiphoton microscopy (MPM). More specifically, the invention pertains to optical designs that can enhance and extend the capabilities of MPM in spectral imaging of biological samples. The unique design of the light collection and the detection optics maximizes the collection of emitted light, thus increasing the signal and hence the signal-to-noise ratio (SNR).

Intranasal Dry Powder Inhaler for Improved Delivery of Vaccines and Therapeutics

This Intranasal Dry Powder Inhaler (DPI), developed with Creare, Inc., allows low-cost delivery of powder vaccines. Nasal delivery has numerous advantages compared to traditional injected vaccines, including: 1) safe, needle-less administration by minimally-trained staff or patient; 2) better protection due to mucosal and cross-protection; and 3) decreased biohazard waste.

Intranasal Nebulizer with Disposable Drug Cartridge for Improved Delivery of Vaccines and Therapeutics

Intranasal delivery is a simple, inexpensive and needle-free route for administration of vaccines and therapeutics. This intranasal delivery technology, developed with Creare LLC., includes low-cost, disposable drug cartridges (DDCs) that mate with a durable hand-held device. The rechargeable-battery-powered device transmits ultrasonic energy to the DDC to aerosolize the drug and is capable of performing for eight hours at 120 vaccinations per hour. Potential applications for this platform technology include intranasal vaccination (e.g.

Real-time PCR and High Resolution Melt Analysis for Genotyping of Chlamydophila psittaci

This nucleic acid assay employs Light Upon Extension (LUX) chemistry and High Resolution Melt (HRM) analysis to detect and distinguish the different genotypes of Chlamydophila psittaci. C. psittaci is an atypical pathogen which may result in severe pneumonia upon infection of birds, mammals and humans (depending on inter-relationships between host and pathogen genotypes). Presently, C. psittaci clinical identification is achieved by a cumbersome and time-intensive mix of ompA gene sequencing, microarray analysis, RFLP and/or serological testing.

Method for Finding Usable Portion of Sigmoid Curve (the Taylor Method), Improved Assay Readouts, and Enhanced Quality Control/Assurance

CDC researchers have developed algorithmic methods for determining sigmoid curve optimums and calculating component concentrations. Sigmoid curves are commonly generated in bioassays and used to calculate results. Various techniques have been used to define the curve, analyze the observations, and calculate a concentration. This technology is an algorithmic approach to identifying the usable portion of a sigmoid curve.

Antigen, Encoding Gene, Related Monoclonal Antibody and Hybridoma Clones for Streptococcus pneumoniae Serological Diagnostics

This CDC developed invention pertains to Streptococcus pneumoniae protein "pneumococcal fimbrial protein A (PfpA)," as well as the encoding pfpA gene. S. pneumoniae linked pneumococcal disease is prevalent among the very young, the elderly and also immunocompromised individuals. This invention covers the breadth of directly PfpA-related technology that might be employed for development of diagnostic tests for S. pneumoniae and/or vaccines directed against the pathogen.
