Laser-capture microdissection (LCM) enables the collection of regions of interest from target tissues, making it compatible with a number of spatially resolved downstream omics applications. Here, we provide a detailed protocol for LCM coupled to ATAC-seq (LCM-ATAC-seq) for the spatial analysis of chromatin landscape based on the method published by Carraro et al. (Cell Rep Methods 3:100598, 2023). LCM-ATAC-seq allows the efficient capture down to single nuclei and can be combined with the morphological staining of target cell populations to characterize chromatin states in fresh-frozen tissue samples.

摘要

Laser-capture microdissection (LCM) enables the collection of regions of interest from target tissues, making it compatible with a number of spatially resolved downstream omics applications. Here, we provide a detailed protocol for LCM coupled to ATAC-seq (LCM-ATAC-seq) for the spatial analysis of chromatin landscape based on the method published by Carraro et al. (Cell Rep Methods 3:100598, 2023). LCM-ATAC-seq allows the efficient capture down to single nuclei and can be combined with the morphological staining of target cell populations to characterize chromatin states in fresh-frozen tissue samples.
