  • Patent number: 11447815
    Abstract: 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.

  • Publication number: 20150220685
    Abstract: A method for determining bias across two domains comprising gene expression data. The method can comprise (a) providing a first domain and a second domain; (b) obtaining information indicative of a bias within the first domain; (c) obtaining information indicative of a bias within the second domain; and (d) using the information indicative of the bias within the first domain and the information indicative of the bias within the second domain to produce an indication of bias across the two domains.

  • Patent number: 8568580
    Abstract: A system for collecting target nucleic acids from a sample can include at least one sample chamber configured to receive a sample containing target nucleic acids and other material, at least one collection chamber removably mountable relative to the at least one sample chamber and configured to collect target nucleic acids separated from the other material, a filter removably mountable relative to the at least one sample chamber and configured to be disposed between the at least one sample chamber and the at least one collection chamber when the at least one collection chamber is mounted relative to the at least one sample chamber.

  • Patent number: 8535878
    Abstract: The present teachings provide methods, compositions, and kits for detecting the presence of protein aggregates. In some embodiments, the protein aggregate is treated with a labeled precursor, and the labeled precursor is incorporated into the protein aggregate to form a labeled protein aggregate. The labeled protein aggregate is then measured, thus detecting the presence of the protein aggregate. In some embodiments, the labeled protein aggregate is detected by interaction of labeled precursors, for example by a proximity ligation assay.
