Novel UNEX Buffer and Disk for Safe Storage and Transport at Ambient Temperatures of Clinical Specimens for Molecular Testing of Pathogens

The development of genomic approaches and nucleic acid based techniques has led to a large number of biological samples, including DNA, RNA, cells, tissues, and environmental samples that require storage. Typically, microbial DNA and RNA samples are stored long-term in laboratory freezers at temperatures ranging from -20°C to -196°C, the lower ranges utilizing liquid nitrogen. This often requires the use of several freezer boxes that can take up space and become difficult to sort through.

Method To Generate Chondrocytes from Human Induced Pluripotent Stem Cells (hIPSCs) and their use in Repairing Human Injury and Degenerative Diseases

This technology includes a method for differentiating human induced pluripotent stem cells (hiPSCs) into stable chondrocytes, capable of producing cartilage, and their use in cartilage repair in human injury and degenerative diseases. In suspension culture, hiPSC aggregates demonstrate gene and protein expression patterns similar to articular cartilage.

Genome Wide DNase I Hypersensitive Sites Detection in Formalin-Fixed Paraffin-Embedded Single Cells

A method of detecting DNase I hypersensitive sites ((DHS) in a single cell or very small number of cells, including cells recovered from formalin-fixed paraffin-embedded (FFPE) tissue slides of patient samples. DHS has revealed a large number of potential regulatory elements for transcriptional regulation in various cell types. The application of DNase-Seq techniques to patient samples can elucidate pathophysiological mechanisms of gene function in a variety of diseases as well as provide potentially important diagnostic and prognostic information.

Generation of Artificial Mutation Controls for Diagnostic Testing

This technology relates to a method of generating artificial compositions that can be used as positive controls in a genetic testing assay, such as a diagnostic assay for a particular genetic disease. Such controls can be used to confirm the presence or absence of a particular genetic mutation. The lack of easily accessible, validated mutant controls has proven to be a major obstacle to the advancement of clinical molecular genetic testing, validation, quality control (QC), quality assurance (QA), and required proficiency testing.

Novel Primate T-cell Lymphotropic Viruses (HTLV, STLV) for Development of Diagnostics, Therapeutics, Research Tools, and Vaccines

CDC researchers have isolated and characterized the novel primate T-lymphotropic viruses denoted human T-lymphotropic viruses 3 and 4 (HTLV-3 and HTLV4), that are believed to have resulted from cross-species transmission at some point in the past. It has been previously established that HTLV-1 causes adult T cell leukemia and other inflammatory diseases; HTLV-2 is considered less pathogenic than HTLV-1 and has been associated with a neurologic disease similar to HTLV-1-associated myelopathy.

Monoclonal Antibody to Detect the Antiretroviral Drug Emtricitabine – for HIV Drug Adherence Monitoring

The U.S. Food and Drug Administration and World Health Organization (WHO) approved the antiretroviral drug emtricitabine (FTC)/ tenofovir disoproxil fumurate (TDF) combination for HIV pre-exposure prophylaxis (PrEP) in high risk populations. Efficacy of PrEP depends strongly on adherence to taking the FTC/TDF pill daily. In the US, the Centers for Disease Control and Prevention (CDC) estimates that 1.2 million Americans will benefit from PrEP. FTC is also a key component of antiretroviral therapy (ART) regimens of HIV-infected persons and significantly associated with adherence.

Improved Protein Quantification Process and Vaccine Quality Control Production

This CDC invention is a method for identifying and quantifying a group of proteins in a complex mixture by a liquid chromatography-tandem mass spectrometry assay. The technology was developed for influenza although it can be used for a wide variety of protein quantification applications. As specifically developed, conserved peptides from the proteins of influenza (hemagglutinin, neuramidase, matrix 1 and 2, and nucleoprotein) have been synthesized and labeled to be used as internal standards for the quantification of those proteins in a complex (biological or manufactured) matrix.

Bicistronic Chimeric Antigen Receptor (CAR) Constructs Targeting CD19 and CD20

CD19 and CD20 are promising targets for the treatment of B-Cell malignancies.  Unfortunately, some clinical studies have shown that there is a loss of CD19 or CD20 expression in various cases of lymphomas and leukemias, particularly after treatment with an agent that targets CD19 (e.g., anti-CD19 CAR-T). However, studies have shown that expression of one protein is retained when the other is lost. This suggests that a therapeutic with the ability to simultaneously target both CD19 and CD20 could represent a solution to the drawbacks of current therapies.
