Monoclonal Antibodies to the HIV-1 Core Protein p24

The core proteins of HIV-1 are secreted into the environment during replication in the human body. The detection of the core protein p24 (molecular mass of 24 kilodaltons) serves as an indicator of early HIV-1 infection, and assays detecting it have been available since the late 1980s. However, the development of a rapid assay for the detection of HIV-1 p24 has only recently become available.

Personalized Cancer Evaluation (PERCEVAL) Method and Software

Cancer represents the leading cause of morbidity and mortality worldwide, with approximately 14 million new cases and 8.2 million cancer related deaths in 2012. This number is predicted to rise by approximately 70% over the next two decades according to the World Health Organization. Prognosis depends heavily on both early detection and frequent monitoring of the patient's response to treatment. Cancerous tumors shed nucleic acids into blood, which can be detected by ultra-deep sequencing of mitochondrial DNA (mtDNA).

Cardiolipin Modification for Immunoassay Detection of Syphilis

Syphilis is a sexually transmitted disease (STD) that remains a global health threat. Syphilis rates in the United States have also been increasing. Left untreated, syphilis infection can span decades and have serious complications including blindness, dementia and paralysis. Syphilis in pregnancy causes prematurity, low birthweight, neonatal death, and infections in newborns. Improvements in syphilis detection are needed to facilitate early diagnosis of active infections and monitor treatment with antibiotics.

Diagnostic Assay with Modified Cardiolipin for Detecting Active Syphilis Infections

Syphilis is a sexually transmitted infection that remains a global health threat. The World Health Organization estimates that more than 12 million new cases are reported in adults annually worldwide. Syphilis rates are rising domestically as well. The rapid plasma reagin (RPR) test (including automated version) and the Venereal Disease Research Laboratory (VDRL) test are commercially available and used to detect/screen active infection.

Monoclonal Antibodies for the Detection of Antiretroviral Integrase Inhibitors

Pre-exposure prophylaxis (PrEP) is a critical component in the fight against HIV but is only effective if persons prescribed PrEP are adhering to the regimens to maintain appropriate drug levels. As PrEP regimens have moved from daily pills to longer lasting injections, the ability to quickly measure and monitor the circulating drug levels of PrEP drugs has increased importance.

Sensitive Method for Detection and Quantification of Anthrax, Bordetella pertussis, Clostridium difficile, Clostridium botulinum and Other Pathogen-Derived Toxins in Human and Animal Plasma

CDC research scientists have developed a method to identify and quantify the activity of pathogenic bacterial adenylate cyclase toxins by liquid chromatography tandem mass spectrometry (LC-MS/MS). Bacterial protein toxins are among the most potent natural poisons known, causing paralysis, immune system collapse, hemorrhaging and death in some cases.

Exposure and Activity Detection Assays for Anthrax Lethal Factor and Lethal Toxin

This CDC developed invention identifies an assay for extremely fast and sensitive detection of Bacillus anthracis lethal toxin (LTx), the toxin responsible for the lethal effects of anthrax infection. This assay has already been successfully tested in animals and will allow for early detection of anthrax exposure and screening of lethal factors to monitor anthrax toxicity, for example for vaccine trial candidates.
