HTAPP_Acquisition and allocation of fresh metastatic breast cancer sample. v1

This standard operating procedure was established by the Center for Cancer Genomics at Dana-Farber Cancer Institute, the Brigham and Women's Hospital and the Klarman Cell Observatory at the Broad Institute, to standardize the collection of fresh metastatic breast cancer biopsies and their allocation to various bulk and single cell assays, including whole exome and bulk RNA-sequencing, single-cell RNA sequencing, and spatial profiling of RNA and protein. The use of a well defined workflow has allowed us to generate high quality data from these different assays, by implementing efficient modes of communication, minimizing the time elapsed from sample collection to preservation or processing, and ensuring optimal transportation conditions.
