Monoclonal Antibody that Detects a Subclass of Dog IgG—for Diagnostic and Research Applications

CDC and collaborating researchers have developed a new monoclonal antibody that recognizes canine IgG (likely IgG4 subclass). This anti-dog IgG reagent could be used to detect antibody reactions to a variety of antigens and has potential use in a wide variety of diagnostic or research applications.

Adjustable Barricade Safety Rail System and Roof Bracket Assembly to Prevent Worker Falls

Falls are the leading cause of death in construction. In 2016, there were 370 fatal falls out of 991 construction fatalities (Bureau of Labor Statistics, Census of Fatal Occupational Injuries data). These deaths are preventable. According to the Occupational Safety and Health Administration, employers must set up the workplace to prevent employees from falling from overhead platforms, elevated work stations, or into holes in the floor and walls.

An Innovative Adapter for Expedited and Automated Thawing of viably Frozen Cells

This technology is a device and system for expediting the thawing frozen specimens (e.g., cryopreserved cells) contained in cryo-vials, offering a breakthrough solution for researchers seeking efficiency and precision in their workflows. The device is equipped with a small elongated tubular adaptor that suspends a cryo-vial of frozen cells over a centrifuge tube containing culture medium in an inverted position. With a focus on speed, efficiency and automation, the adaptor dramatically expedites the process of recovering viable cells from frozen specimens.

Trans-auricular Left Atrial Appendage Ligation to Prevent Thrombosis

This technology includes an interventional device to occlude the left atrial appendage to prevent thrombus formation. Atrial fibrillation is the most common cardiac arrhythmia and is associated with formation of thrombus in the left atrial appendage. Standard preventative treatment involves anticoagulation, which is not tolerated by all patients. Existing devices necessitate improvement because they need trans-septal puncture and anticoagulation to prevent thrombus or are prone to life-threatening complications.

Novel One-Well Limiting-Antigen Avidity Enzyme Immunoassay to Detect Recent HIV-1 Infection Using a Multi-subtype Recombinant Protein

This CDC developed Limiting-Antigen avidity Enzyme Immunoassay (LAg-avidity-EIA) provides an easy way to measure increasing binding strength (avidity) of HIV antibodies as part of maturation HIV antibodies after seroconversion, providing a method to distinguish early-stage from long-term HIV-1 infection. Surveillance of HIV-1 provides information on prevalence rates of the disease, but determination of new infection rates (HIV-1 incidence) is difficult to deduce. Longitudinal follow up is expensive and can be biased.

Minibody for Conditioning prior to Hematopoietic Stem Cell and Progenitor Cell Transplantation

Patient conditioning is a critical initial step in hematopoietic stem and progenitor cell (HSPC) transplantation procedures to enable marrow engraftment of infused cells. Conditioning regimens have traditionally been achieved by delivering cytotoxic doses of chemotherapeutic agents and radiation. However, these regimens are associated with significant morbidity and mortality, and cannot be used safely in elderly or subjects with comorbidities.
