ANTIBODY-LINKED IMMUNO-SEDIMENTATION AGENT AND METHOD OF ISOLATING A TARGET FROM A SAMPLE USING SAME
20230417743 · 2023-12-28 ·

The present disclosure is directed to antibody-linked immuno-sedimentation agent, the antibody being linked to a sedimentation agent by a non-antigen binding region of the antibody, and a method of isolating a target from a sample using the antibody-linked immuno-sedimentation agent. The methods involve forming a mixture including a sample with an antibody linked immuno-sedimentation agent and red blood cells under conditions sufficient to form red blood cell rouleaux and allow antibody-antigen binding.

Target cell concentration using dielectrophoresis (DEP)

Methods and devices for concentrating target cells using dielectrophoresis (DEP) are disclosed. The method allows relatively high throughput of sample through a microfluidic device in order to allow rapid capture of target cells even when they are present in low concentrations within the sample. The method utilizes multiple chambers through which samples will flow, the chambers arranged such that the first capture area has a larger area and faster flow rate than a second chamber, the second chamber being positioned downstream of the first capture area and being smaller with a slower flow rate to further concentrate the material captured in the first capture area.

20210032312 · 2021-02-04 ·

Fibronectin type III domains (FN3) that specifically bind to CD8A, related polynucleotides capable of encoding CD8A-specific FN3 domains, cells expressing the FN3 domains, as well as associated vectors, and detectably labeled FN3 domains are useful in therapeutic and diagnostic applications.

Corneal endothelial cell marker

The purpose of the present invention is to provide a method of purification and preparation of cultured corneal endothelial cells, and in particular, to provide cell surface markers for use in corneal endothelial cells not including transformed cells. Provided are cell markers for distinguishing normal cells and transformed cells, in particular normal and transformed corneal endothelium cells. These cell markers relate to specific cell surface markers, for example, to a normal corneal endothelial surface marker such as CD166, and a transformed cell surface marker such as CD73. By using the transformed cell surface marker such as CD73 to remove transformed cells by sorting, it becomes possible to improve purity of a normal cultured corneal endothelium. By using normal corneal endothelial surface marker such as CD166, or by combined use with the transformed cell surface marker, it becomes possible to provide a means for verifying the purity of a prepared corneal endothelium.

Disclosed are methods and systems for analyte detection in a sample and more particularly, a biological sample. Methods and systems particularly relate to differentiating and/or identifying cell types in biological samples, such as blood samples, by adding antibodies specific to predetermined CD antigens. Other methods and systems relate to controlling the dynamic range of an assay for analyte detection.

Cell detection method
11060964 · 2021-07-13 · ·

Provided is a cell detection method which makes it possible to effectively and accurately perform gene analysis only on target cells. The cell detection method includes a sorting step of obtaining first information derived from cells in a sample solution by using a flow cytometry method and sorting target cells into a container having arrays of wells each having an opening based on the first information, an imaging step of imaging the cells sorted into the container, and a determination step of obtaining second information derived from cells based on the image of the cells captured by the imaging step and determining cells to be analyzed from the sorted cells.

Circulating astrocytes and MFSD2A as biomarkers
11054422 · 2021-07-06 · ·

The invention provides the use of circulating astrocytes (cAstr) and the Major Facilitator Superfamily Domain containing Protein 2a (Mfsd2a) as biomarkers, and their combined use with other related circulating markers (cBMEC and EPC) in early detection and diagnosis of cerebrovascular diseases (CVD) or central nervous system (CNS) disorders.

Microfluidic device for cell separation and uses thereof

Methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal blood) include introducing a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).
