Antigen-capture Electrochemiluminescent Assay for Determining Rabies Vaccine Potency

CDC researchers developed a more efficient method of assessing rabies vaccine potency using an antigen-capture electrochemiluminescent (ECL) assay. This assay utilizes SULFO-NHS-Ester labeled murine monoclonal antibodies to quantify glycoprotein concentration, which is an indicator of vaccine potency. Currently, the potency of rabies vaccines is determined by the effective-dose (ED50) mouse study evaluation method, which is more than 50 years old.

Composition and Methods for Rapid Detection of HIV by Loop-mediated Isothermal Amplification

This invention relates to methods and compositions for rapid detection of HIV nucleic acids in a biological sample. Specifically, it involves the use of the loop-mediated isothermal amplification (LAMP) for rapid detection of HIV-1 and/or HIV-2. The use of rapid HIV tests is highly attractive for screening of patient samples, especially in developing countries where resources are limited, because they are quick, easy to perform, and do not require any special equipment.

Rapid Detection of Multi-Drug-Resistant Mycobacterium tuberculosis Using Real-Time PCR and High-Resolution Melt Analysis

CDC scientists have developed a rapid, sensitive, and specific real-time PCR assay that is capable of detecting the presence of Mycobacterium tuberculosis and determining its resistance profile to antibiotics, such as rifampicin and isoniazid. Currently, there are few assays available that are capable of both detecting M. tuberculosis and determining the bacteria's drug resistance. This assay incorporates multiple fluorescent chemistries, providing a simple and cost-effective method of determining the bacteria's drug resistance.

Use of Vitronectin as a Biomarker for the Detection of Dengue Hemorrhagic Fever

Dengue hemorrhagic fever (DHF) is a severe, potentially deadly infection spread by mosquitos. CDC scientists have identified vitronectin as an important biomarker of DHF. They have shown vitronectin is significantly reduced in DHF and severe dengue infections when compared to dengue non-hemorrhagic fever patients. Presently, DHF is established by assessing antibody concentrations and other rule-of-thumb criteria, but often these assays can be difficult to interpret and lead to false conclusions.

Multiplex Assay for Detection of Dengue Virus

Dengue virus (DENV) is the cause of dengue illness (dengue fever, dengue hemorrhagic fever, and dengue shock syndrome). CDC researchers have developed a RT-PCR multiplex assay that, prior to sero-conversion, selectively detects dengue virus in biological or other fluid media, such as whole blood, plasma, or serum. The primers and probes from this assay are sufficiently specific to amplify and detect all four DENV serotypes. This FDA-approved technology may provide an improved method for rapid and accurate serotyping of dengue virus in clinical and research settings.

NIAID TTIPO’s extraordinary efforts in “COVID-19 Technologies Licensed Globally Through WHO Program” was recognized by the Licensing Executives Society (U.S.A. & Canada) in 2022 with a Deals of Distinction Award in the Industry-University-Government Interface Sector. This award acknowledged the collaborative efforts put forth by the WHO, Medicines Patent Pool (MPP) and the NIH for COVID-19 technologies licensed globally through the WHO program.

CDC’s Assay for Global Surveillance of Drug-resistant HIV-1 Was Commercialized

FLC logo

Researchers at the Centers for Disease Control and Prevention (CDC) developed a low-cost technology to rapidly detect HIV-1 drug resistance (HIVDR) in plasma and dried blood spot (DBS) samples with 95.8% genotyping sensitivity. CDC’s partners at Life Technologies Corporation (“LifeTech”) have licensed, further developed, and incorporated the technology into a commercialized product. Life Tech’s HIV-1 Genotyping Kit provides a cost-effective assay, scalable workflow, easy-to read sequencing results, and robust test performance.

Parvovirus B19 Diagnostic Test Kit

FLC Logo

This development is the first and only FDA approved diagnostic test kit for parvovirus B19. Parvovirus B19 infection in pregnancy is often overlooked simply because most infected pregnant women are asymptomatic or have only mild manifestations, such as slight itching. However, pregnant women (in the first and second trimesters) with the B19 infection can give rise to serious fetal complications during pregnancy. Up to 50% of women are susceptible to parvovirus B19 infection. The B19 infection may result in anemia, pregnancy miscarriage and/or other problems.

Accelerated Magnetic Resonance Imaging (T-SENSE)

FLC Logo

This new, accelerated magnetic resonance imaging (MRI) method reduces the total imaging time for lengthy scans. The method may be used for imaging dynamic events such as heart motion or brain activity. The technology exploits the spatial and temporal correlation of magnetic resonance signals by combining parallel imaging and temporal filtering to achieve a new MRI technique referred to as (TSENSE). The TSENSE method has a higher degree of artifact suppression using parallel imaging and temporal filtering.
