摘要： The present invention generally relates to a set of early developmental reference data or “lineage scorecard” for stem cells, and methods, systems and kits to generate a lineage scorecard for predicting the functionality and suitability of stem cell lines. In some aspects, methods for generating a scorecard comprises measuring the gene expression of a plurality of early developmental genes, such as pluripotent, early ectoderm, early mesoderm and early endoderm genes to predict the pluripotency and differentiation potential of the stem cell line and its functionality and/or suitability for a desired use. In some embodiments, a reference scorecard can be compared with the test stem cell line scorecard to accurately predict the utility and/or identify specific characteristics of the stem cell line, e.g., to determine its suitability for downstream applications, e.g., therapeutic use, drug screening, toxicity assays, differentiation into a desired cell lineage, etc.

摘要： The present invention relates, e.g., to a composition comprising peptides represented by SEQ ID NO:1, or active variants thereof, wherein the peptides or active variants can bind specifically to an antibody induced by a causative agent of Lyme disease (a pathogenic Borrelia), e.g. in a sample from a subject having Lyme disease. Compositions of the invention may comprise multiple peptides, from multiple proteins. Diagnostic kits comprising the peptides are described, as are diagnostic assays using the peptides.

摘要： The present invention is directed to a nucleic acid detection device and method that incorporates bio-nanosensor technology to detect duplex DNA. The device is particularly applicable in detecting the presence or absence of duplex DNA and its correlation to the diagnosis of infectious diseases. In one embodiment, the infectious disease is Lyme disease or a bacterial or viral infection. The device comprises a bio-nanosensor element comprising ssDNA primed nanotubes, either single walled or multi-walled. The method comprises contacting the bio-nanosensor element with a test solution potentially containing DNA of interest. DNA of interest that hybridizes to the ssDNA results in a measurable change in the electrical properties of the bio-nanosensor. Correlations between the results provided by the device and the presence of disease states can result in rapid diagnosis of diseases such as Lyme disease or foodborne infections such as salmonellosis.
