Abstract
- Resolving the complexity of the human brain at the level of single cells is essential to gaining an understanding of the immense diversity of cell types and functional states in both healthy and diseased brains. To exploit fully the technologies available for such studies, one must extract and isolate pure nuclei from unfixed postmortem tissue while preserving the molecules to be interrogated. Currently, nuclei are necessary substitutes for individual brain cells, since myriad cell types/sub-types constituting the human brain are embedded within the neuropil-a complex milieu of interconnected cells, processes, and synapses-which precludes intact and selective isolation of single brain cells. Here, we describe a protocol for the extraction and purification of intact single nuclei from frozen human brain tissue along with modifications to accommodate numerous downstream analyses, particularly for transcriptomic applications.<br /> (© 2023.
