Specimen enrichment for optical tomography cell analysis

A method for enhancing gating performance of a cell sorter to prepare an enriched specimen for optical tomography cell analysis includes introducing a specimen into a FACS to generate 2D event data; generating a first scatterplot of the 2D data; identifying target objects; constructing a boundary within the first scatterplot to produce a first gate; counting target objects within the first gate; comparing the number of target objects within the first gate to a first predetermined value and adjusting the first gate as necessary. A boundary around a set of target objects is constructed in a second scatterplot to produce a subset second gate and target objects within the second gate are counted and the count compared to a second predetermined value. When a boundary around target objects meets specifications the first and second gates are stored in memory and used to enrich patient specimens.

General strategy for antibody library screening

A generally applicable method for the selective covalent attachment of a reporter molecule to a replicating entity that allows one to obtain specific binders from a single round of library screening is disclosed. For example, selective biotinylation of phage particles and yeast cells displaying a binder to any given target can be achieved via application of a coupled enzyme reaction that includes a peroxidase, an oxidase and a catalase.

HIGHLY-MULTIPLEXED FLUORESCENT IMAGING

Provided herein is a method and system for analyzing a sample. In some embodiments the method makes use of a plurality of capture agents that are each linked to a different oligonucleotide and a corresponding plurality of labeled nucleic acid probes, wherein each of the labeled nucleic acid probes specifically hybridizes with only one of the oligonucleotides. The sample is labeled with the capture agents en masse, and sub-sets of the capture agents are detected using iterative cycles using corresponding subsets of the labeled nucleic acid probes.

Point of care assays to detect the status of tuberculosis infection

Point of care methods to detect the probability or status of tuberculosis infection in individuals by determining presence or absence of one or more peptide of SEQ ID NOS:1-22 in a biological fluid of a subject are described. These methods may be assays based on affinity reagents specifically reactive with these peptides.

Extracellular vesicle comprising a fusion protein having Fc binding capacity

The present invention pertains to extracellular vesicle (EV) therapeutics, wherein the EVs are coated with proteins containing Fc domains (such as antibodies) for i.a. targeting and therapeutic applications. The coating of EVs is achieved through inventive protein engineering of EV polypeptides. The present invention thus relates to methods for coating of EVs, EVs per se, as well as pharmaceutical compositions and medical applications of such EVs coated with Fc containing proteins.
