Abstract:
The invention provides methods and compositions for separately denaturing a probe and target in hybridization applications. The invention may, for example, eliminate the use of or reduce the dependence on formamide in hybridization applications. Compositions for use in the invention include an aqueous composition comprising at least one polar aprotic solvent in an amount effective to denature double-stranded nucleotide sequences.
Abstract:
A sample processing system that may be automated and methods are disclosed where samples are arranged on a carrier element and a process operation control system automatically processes the samples perhaps robotically with an operationally-influential exteriorly-consequential information monitor or a data capture element. Significant process details as well as operationally-influential exteriorly-consequential information may be monitored and an automatic notice element may cause notification of a person at some display that may be remote. Various people may be notified, such as an administrator, a supplier, or a manufacturer of an opportunity for some action such as reagent reordering or the like. A simulated motion display may be included to “watch” simulated operation in real time or long after completion of the actual processing.
Abstract:
This invention is directed to methods, kits, non-nucleotide probes as well as other compositions pertaining to the suppression of binding of detectable nucleic acid probes to undesired nucleotide sequences of genomic nucleic acid in assays designed to determine target genomic nucleic acid.
Abstract:
Methods and apparatuses for analyzing digital pathology images are provided. The methods and apparatuses may provide estimates of staining intensity and proportion score in regions of interest within an image. Digital pathology images may be scored according to these metrics. The methods and apparatuses disclosed herein utilize various predetermined thresholds, parameters, and models to increase efficiency and permit accurate estimation of characteristics of a stained tissue sample.
Abstract:
Methods and systems for image scoring and analysis are provided. Scored and analyzed images may include digital pathology images. Image scoring and analysis methods may include techniques to identify nuclei and determine membrane staining extent through the use of a priori models. Image scoring and analysis methods may include techniques for membrane intensity determination. Images may be scored based on an extent of membrane staining and membrane intensity.
Abstract:
The present invention relates to a method of biological labeling that occurs via a free radical chain reaction. The labeling occurs due to deposition of a detectable reporter molecule from a media comprising a substance comprising at least two moieties of a peroxidase enzyme substrate (termed herein ‘cross-linker’) in a target site comprising peroxidase activity and a biological marker. The labeling reaction described herein may generally be used to detect targets in a host of experimental schemes for detecting and visualizing a biological or chemical target, including immunohistochemistry (IHC), in situ hybridization (ISH), antibody-based staining methods such as ELISA, Southern, Northern, and Western blotting, and others.
Abstract:
Disclosed is a microwave heater and a method of heating. The microwave heater includes a non-modal interplate microwave applicator and may include a nonresonant enclosure. The non-modal interplate microwave applicator is configured to receive therein a load to be heated by microwaves radiated from the non-modal interplate microwave applicator.
Abstract:
The invention provides compositions and methods for the detection of targets in a sample; in particular, an immunohistochemistry (IHC) sample. Probes and detectable labels may be provided in multiple layers in order to increase the flexibility of a detection system, and to allow for amplification to enhance the signal from a target. The layers may be created by incorporating probes and detectable labels into larger molecular units that interact through nucleic acids base-pairing, including peptide-nucleic acid (PNA) base-pairing. Optional non-natural bases allow for degenerate base pairing schemes. The compositions and methods are compatible with immunohistochemistry (IHC), but also could be used in immunocytochemistry (ICC), in situ hybridization (ISH), flow cytometry, enzyme immuno-assays (EIA), enzyme linked immuno-assays (ELISA), blotting methods (e.g. Western, Southern, and Northern), labeling inside electrophoresis systems or on surfaces or arrays, and precipitation, among other general detection assay formats. The invention is also compatible with many different types of targets, probes, and detectable labels.
Abstract:
A computer system for analyzing a specimen processing workflow in a pathology laboratory including a display and a processor configured to provide a first interface, a second interface, and a third interface to the display, receive, via the first interface, a first set of parameters associated with an existing specimen processing workflow in a pathology laboratory, the first set of parameters including a workflow process and a workflow scale, and determine, based on the first set of parameters, current performance data of the existing specimen processing workflow having an associated current cost information and current time utilization. The processor may further be configured to receive, via the second interface, a second set of parameters associated with a proposed modification to the existing specimen processing workflow, the second set of parameters including parameters associated with at least one laboratory device, determine, based on the first and second sets of parameters, revised performance data having an associated revised cost information and revised time utilization, and provide an output comprising a comparison between revised performance data and the current performance data.
