摘要:
A differentiation system for differentiating cells is described. A differentiation system comprises an input means for receiving holographic image data of a microscopic particle in suspension, a holographic image data processing means for converting the holographic image data to the frequency domain by performing a Fourier transform of the holographic image data, and a recognition means for determining characterization features of the holographic image data of the microscopic particle in the frequency domain for characterization of the microscopic particle, the characterization features comprising rotationally invariant features.

Disclosed herein are apparatus, systems, and methods for optically identifying and enumerating cells present in a blood sample. A light scatter detector array may be used having no more than three light scatter detectors. The array may include a side scatter detector, an intermediate angle light scatter detector, and one of an axial light loss detector and a forward light scatter detector. A lytic reagent system is disclosed that allows for the identification and enumeration of five major leukocyte populations in normal whole blood on an instrument using no more than three light scatter detectors.

Methods for processing whole blood samples are provided. Aspects of the methods include depleting leukocytes from a whole blood sample to produce a leukocyte depleted sample, and then lysing red blood cells (RBCs) in the resultant leukocyte depleted sample to produce a leukocyte/RBC depleted sample. Also provided are compositions and kits for practicing embodiments of the invention. The methods and compositions find use in a variety of different applications, including the detection of circulating tumor cells (CTCs).

This disclosure describes methods, kits, and systems for scoring the immune response to cancer through examination of tissue infiltrating lymphocytes (TILs). Methods of scoring the immune response in cancer using tissue infiltrating lymphocytes include detecting CD3, CD8, CD20, and FoxP3 within the sample and scoring the detection manually or scoring the digital images of the staining with the aid of image analysis and algorithms.
摘要:
Die Erfindung betrifft ein in-vitro Verfahren zum markierungsfreien Bestimmen eines Zelltyps einer Zelle (10) in einer biologischen Probe, wobei eine Mikroskopiervorrichtung (14) ein Höhenprofil (18) der Zelle (10) gegenüber einer Trägerplatte (16) erfasst (S1). Das Verfahren ist gekennzeichnet durch die durch eine Zellanalyseeinrichtung (13) durchgeführten Schritte: Ermitteln eines Zellkompartiments (12, 12', 12'') der Zelle (10) anhand des erfassten Höhenprofils (18, S2), Ermitteln eines vorbestimmten quantitativen Zellmerkmals anhand des ermittelten Zellkompartiments (12, 12', 12'', S3), und Bestimmen des Zelltyps der Zelle (10) anhand des ermittelten quantitativen Zellmerkmals (S3). Die Erfindung betrifft ebenfalls eine entsprechend eingerichtete Zellanalyseeinrichtung (13) und eine entsprechende Mikroskopiervorrichtung (14).
摘要:
Disclosed are apparatus and methods for analyzing bodily fluids, such as blood samples, using an integrated hematology analyzer and flow cytometer system. Under the present approach, an integrated system may operate as a closed fluidic system or an open fluidic system, and may selectively perform automated hematologic protocols, flow cytometer protocols, and custom protocols. Such apparatus may, for example, identify and enumerate multiple cell types in whole blood based on cellular morphology, analyze cellular immunoassays using antibodies labeled to cells, and also detect low abundant analytes in whole blood as well as serum and other bodily fluids not attached to cells using bead-based immunoassay methods. The system may include a fluid handling system to control sample flow, an optical transducer that includes a flow cell, optical detectors for light scatter and/or fluorescence, and also an illumination source.
