RESUMEN
In order to process samples by fluorescence-activated cell sorting (FACS), it is essential to obtain a single-cell suspension of dissociated cells. Numerous protocols and commercial reagents are available; however, each requires optimization for specific tissue types. Here, we describe an optimized protocol for dissociating dissected chick embryos across a broad span of developmental stages. We also provide protocols for processing targeted cell populations isolated using FACS for ATAC-seq, RNA-seq, and chromatin immunoprecipitation. For complete details on the use and execution of this protocol, please refer to Ling and Sauka-Spengler (2019) and Williams et al. (2019).
