    摘要: Systems and methods for detecting microsatellite instability in a biological sample are described. Signal data is received from a capillary electrophoresis genetic analysis instrument, wherein the signal data is measured from fluorescence of fragments comprising nucleic acid sequences amplified from the biological sample via polymerase chain reaction (PCR). The nucleic acid sequences correspond to a plurality of different microsatellite loci and are obtained using a plurality of PCR primers configured to flank a plurality of microsatellite loci of a biological sample. When the PCR primers and the biological sample are combined and subjected to PCR amplification, fluorescently labeled DNA fragments are generated comprising the plurality of microsatellite loci. Fluorescent data obtained from the plurality of fluorescently labelled microsatellite loci are used to classify microsatellite instability of the biological sample.

    摘要: A proximity binding assay (PBA) is performed on at least one test sample, at least one reference sample, a background sample, and one or more calibration samples using a thermal cycler instrument. Ct values are determined for at least one set of test sample data and at least one set of reference sample data. Background corrected Ct values are calculated using a corresponding value in a background sample data set. A linear range is determined for the background corrected Ct values as a function of sample quantity. A linear regression line is calculated for each linear range. One or more parameter values of an exponential model (EM) fold change formula are estimated from the one or more sets of calibration sample data. A target protein quantity and associated confidence interval are calculated using the linear regression lines and the EM fold change formula.

    摘要: A computer-implemented method for determining minor variants. The method includes receiving electropherogram sequence data from a test sample, identifying any non-primary peaks in the electropherogram, and characterizing identified non-primary peaks using at least one signal feature. The method may further include analyzing the at least one signal feature across identified non-primary peaks to identify variant candidates, evaluating at least one peak characteristic of each of the identified variant candidates, and classifying variant candidates as bona fide variants based on the evaluation of peak characteristics.

    摘要: Various embodiments of methods for analyzing proximity binding assay (PBA) data are disclosed. Proximity binding assays as a class of analyses offer the advantages of the sensitivity and specificity of biorecognition binding, along with the exponential signal amplification offered by a variety of oligonucleotide amplification reactions, such as the polymerase chain reaction (PCR). However, as various proximity binding assays have reaction kinetics governed by an additional step of the binding of a biorecognition probe (BRP) with a target molecule, there is a need for methods for the analysis of PBA data that are particularly suited to the unique characteristics of such data.
