This invention provides materials, methods, and assays for detecting HIV-1 groups M and O and optionally HIV-1 group N and simian immunodeficiency virus-cpz (SIV-cpz). Specific nucleic acid primers for hybridization, amplification, and detection of HIV-1 are also provided for. The nucleic acid amplification assays can detect small concentrations of HIV-1 and are also useful for quantitative examinations of viral load concentrations within biological samples.

Available for nonexclusive licensing as a research material is a conditionally immortalized Organ of Corti cell line called OC-k3. Sensory cells from the auditory organ, the Organ of Corti, are terminally differentiated and cannot be cultured. Moreover, few of them can be isolated per cochlea and survive only few hours after isolation making impossible to use on them many biochemical and molecular biology techniques. OC-k3, expresses many markers of sensory cells and it has already been used as an in vitro model for a variety of studies.

Counterfeit drugs (also known as “fake or falsified medicines”) have become a major world-wide public health concern. Falsified medicines may contain toxic substances, the wrong active ingredients, suboptimal amounts of active ingredients, or no active ingredients at all. CDC researchers developed a portable (handheld), battery-operated, and relatively inexpensive device that non-trained personnel can use quickly to evaluate a particular branded tablet for authenticity.

The technology relates to a protein-based nanoparticle platform that allows presentation of immunogenic molecules such as influenza virus antigens. This protein platform is made up of hepatitis B capsid/core proteins. The core proteins contain immunogenic loop c/e1, where other antigens can be inserted and the chimeric protein retains the ability to form capsid-like particles. The technology describes the insertion of one or more copies of influenza epitopes derived from the globular head or the stem region of hemagglutinin protein into or around the c/e1 loop of the core protein.

A respirator protects the wearer from inhaling dangerous substances, such as chemicals and infectious particles. CDC developed devices and methods to detect and remove chemicals such as hydrogen cyanide, cyanogen, hydrogen sulfide, nitrite, and nitric oxide from the air for those wearing respirators. Cobinamide (a Vitamin B12 analog with a high affinity to cyanide) molecules are immobilized within a silica matrix that allows for the infiltration and containment of gaseous chemicals.

There is a great need for broadly protective, “universal” influenza virus vaccines given the antigenic drift and shift of influenza viruses and the variable protective efficacy of the current influenza vaccines. This technology relates to a broadly protective, “universal” influenza vaccine candidate composed of a cocktail of different low pathogenicity avian influenza virus subtypes inactivated by betapropiolactone (BPL).
