    摘要: Systems and methods for inferring a status of a cell population are provided. Described techniques allow deconvolving a first clonal population comprising a first plurality of cells of a species, wherein nucleic acid sequence reads from each cell in the first plurality of cells are obtained. The nucleic acid sequence reads are mapped into bins representing portions of a reference genome, and a pattern of sequence read counts for each cell across the multiple bins is used to assign a cell to a group, thereby inferring a mitotic status of the cell. The assignment of nucleic acid sequence reads into bins is also be used for segregating cells into classes based on a status of a certain biological marker in each cell. Comparison of sequence read counts for a subset of bins across the cell classes allows evaluating effect of a compound on a cell status.

    摘要: The present disclosure provides methods of processing or analyzing a sample. A method for processing a sample may comprise hybridizing a probe molecule to a target region of a nucleic acid molecule (e.g., a ribonucleic acid (RNA) molecule), barcoding the probe-nucleic acid molecule complex, and performing extension, denaturation, and amplification processes. A method for processing a sample may comprise hybridizing first and second probes to adjacent or non-adjacent target regions of a nucleic acid molecule (e.g., an RNA molecule), linking the first and second probes to provide a probe-linked nucleic acid molecule, and barcoding the probe-linked nucleic acid molecule. One or more processes of the methods described herein may be performed within a partition, such as a droplet or well. One or more processes of the methods described herein may be performed on a cell, such as a permeabilized cell.

    摘要: The present disclosure provides systems and methods for making a hydrogel comprising a cell, cell nucleus, or one or more components derived from a cell or cell nucleus. A method for making a hydrogel may comprise providing a cell or cell nucleus, a first polymer, wherein the first polymer comprises a plurality of first crosslink precursors, each of the plurality of first crosslink precursors comprising an azide group; providing a second polymer, wherein the second polymer comprises a plurality of second crosslink precursors, each of the plurality of second crosslink precursors comprising an alkyne group; and crosslinking the first polymer and the second polymer via a reaction between a first section of the first crosslink precursors and a second section of the second crosslink precursors, thereby providing the hydrogel comprising the cell or cell nucleus.
