摘要： The invention employs an unlabeled signal primer comprising a 5′ adapter sequence for detection of variations in nucleic acid target sequences. The detection system further comprises a reporter probe, the 3′ end of which hybridizes to the complement of the 5′ adapter sequence of the signal primer to produce a 5′ overhang. Polymerase is used to fill in the overhang and synthesize the complement of the 5′ overhang of the reporter probe. Synthesis of the reporter probe complement is detected, either directly or indirectly, as an indication of the presence of the target.

摘要： A high-sensitivity, low-background immuno-amplification assay is provided, which offers a streamlined workflow suitable for high-throughput assays of clinically relevant samples, such as blood and other bodily fluids. The assay comprises the use of two proximity members that each comprise an analyte-specific binding component conjugated to an oligonucleotide. Binding an analyte brings the oligonucleotide moieties of the proximity members in sufficiently close contact that the oligonucleotides form an amplicon. The presence of the analyte then is detected through amplification of the amplicon and detection of the amplified nucleic acids. The sensitivity of the assay of the present invention is improved by preventing spurious or non-specific amplicon formation by proximity members that are not complexed with an analyte.

摘要： Methods for predicting the development of sepsis in a subject at risk for developing sepsis are provided. In one method, features in a biomarker profile of the subject are evaluated. The subject is likely to develop sepsis if these features satisfy a particular value set. Methods for predicting the development of a stage of sepsis in a subject at risk for developing a stage of sepsis are provided. In one method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to have the stage of sepsis if these feature values satisfy a particular value set. Methods of diagnosing sepsis in a subject are provided. In one such method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to develop sepsis when the plurality of features satisfies a particular value set.

摘要： A direct chemical lysis composition includes an assay compatible buffer composition and an assay compatible surfactant. When combined with a specimen storage composition, such compositions prevent undesired modifications to nucleic acid and proteins lysed from cells in the biological sample. Assays of samples from such compositions do not require expensive and time-consuming steps such as centrifugation and prolonged high temperature processing. The direct chemical lysis composition of the present invention permits direct nucleic acid extraction from the cells in the biological sample without the need to decant off the transport media or otherwise exchange the transport media with assay compatible buffers. There is no need to combine the sample with proteinase K or another enzyme to extract nucleic acids from the cells. A method for lysing cells to obtain target nucleic acid for assay and a kit for combining the direct chemical lysis composition with a sample are also contemplated.
