KCNN4 Knockout Mice for Mechanistic Research

This technology includes a transgenic allele for a mouse knockout model for the KCNN4 gene. Secretion of fluids from these salivary glands requires the coordination of multiple water and ion channel proteins. Notably, the majority of these channels have been shown to be up-regulated by increased calcium concentrations. The relevant calcium-activated potassium channels are split into the small, intermediate, and large conductance channels (called the SK, IK, and BK channels). The KCNN4 gene plays a part in the IK and BK channels.

Polyclonal Antibodies to Apolipoprotein L1 for Use in Basic Science Research

This technology includes antibodies to apolipoprotein L1 (ApoL 1) to be used in basic science laboratory studies. ApoL 1 is a protein that is present within cells and circulates as component of high-density lipoprotein. Its functions are not well understood. Recently APOL 1 genetic variants have been shown to be highly associated with kidney disease in African Americans.

Monoclonal Antibodies to HIV-1 Vpr

Available for licensing are monoclonal antibodies against HIV-1 viral protein R (Vpr) and the respective hybridoma cell lines expressing the same. The antibodies provide a means for detecting HIV-1 Vpr. Currently, the mechanism of HIV pathogenesis believed to involve viral replication inside immune cells and other cells. At present, there are no clinical assays for detecting HIV-1 Vpr. Vpr circulates at detectable levels in the blood and is likely derived from degraded virions or released from infected cells. Vpr facilitates viral replication and disrupt normal cell function.

A Highly Efficient Differentiation Protocol for Placental Cells Derived from Human Pluripotent Stem Cells

This technology includes a robust and highly efficient protocol that differentiates human pluripotent stem cells (hPSCs) into the developmental precursor of placental cells, the trophectoderm (TE), under chemically defined conditions. The in vitro generation of TE cells holds great promise for modeling diseases of the placenta, drug screening, and cell-based therapies.

Monoclonal Antibodies for Detection of Stachybotrys chartarum (a Fungus)

CDC NIOSH researchers have developed a simple and rapid detection technique for Stachybotrys chartarum (a type of mold that commonly grows on wet building materials) by producing monoclonal antibodies which reacts with proteins in Stachybotrys chartarum. These antibodies can be used in immunologic detection assays to detect and possibly quantify Stachybotrys chartarum in environmental samples, and to our knowledge, they do not cross react with other fungi.

Nucleic Acid Detection of the Fungal Pathogen Histoplasma capsulatum from Clinical and Environmental Samples

This invention relates to detecting Histoplasma capsulatum by PCR using oligonucleotide probes specific for the fungus. Histoplasmosis is a mycotic infection of varying severity, usually localized in the lungs. Caused by H. capsulatum, infections are usually symptomatic but can develop into chronic disease, especially in immunocompromised individuals.

Diisocyanate Specific Monoclonal Antibodies for Occupational and Environmental Monitoring of Polyurethane Production Exposure-related Asthma and Allergy and Clinical Diagnosis

CDC researchers have developed monoclonal antibodies useful as diagnostics for diisocyanate (dNCO) exposure and for toxicity characterization of specific dNCOs. Currently, dNCOs are used in the production of all polyurethane products and are the most commonly reported cause of occupational-induced asthma and also linked to allergic contact dermatitis. Presumptive diagnosis of dNCO asthma is presently dependent on criteria such as work history, report of work-related asthma-like symptoms and nonspecific airway reactivity to methacholine challenge.

Warning System for Mobile Machinery Hazardous Zones

This invention relates to a warning system designed to protect individuals working near hazardous machinery. The system consists of a proximity-warning transmitter mounted to hazardous machinery and a receiver, worn by a worker, capable of detecting the transmitter signal. This worker-safety system can incorporate visual alerts and audible alerts. It also allows automatic shutdown of machinery upon receiver activation and may be particularly useful in the mining industry.

Personal Air Sampler for Collecting Airborne Aerosol Particulates for Molecular Analysis by Size

This invention consists of a sampling apparatus that utilizes one or more cyclone separators to collect airborne particles from the atmosphere. The apparatus not only separates out aerosols from the atmosphere, but also serves as a collection tube for aerosol particles. Through its unique design, this CDC-developed apparatus is able to use the centrifugal force of the air flow on aerosolized particles forcing them to separate by size. Since the sample is collected directly in a microcentrifuge tube, in situ analysis of the ambient particulates can be performed.
