The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing and analyte characterization from a single cell. Such polynucleotide processing may be useful for a variety of applications. The compositions, methods, systems, and devices disclosed herein generally describe barcoded oligonucleotides, which can be bound to a bead, such as a gel bead, useful for characterizing one or more analytes including, for example, protein (e.g., cell surface or intracellular proteins), genomic DNA, epigenetic information (e.g., accessible chromatin, DNA methylation), and RNA molecules (e.g., mRNA or CRISPR guide RNAs). In some cases, the disclosed methods comprise analysis of analytes from a cell using a cell bead.
本公开提供了用于单细胞多核苷酸处理和分析表征的组合物、方法、系统和设备。这种多核苷酸处理可用于多种应用。本文公开的组合物、方法、系统和装置一般描述了条形码寡核苷酸,它们可与凝胶珠等珠子结合,用于表征一种或多种分析物,包括蛋白质(如细胞表面或细胞内蛋白质)、
基因组 DNA、表观遗传信息(如可触及的染色质、DNA 甲基化)和 RNA 分子(如 mRNA 或 CRI
SPR 引导 RNA)。在某些情况下,所公开的方法包括使用细胞珠分析细胞中的分析物。
