HTAPP_CST- Nuclei isolation from frozen tissue v2

This protocol describes amethodbased on work by Drokhlyansky et al.for nuclei isolation from frozen tissue.It can be used on both healthy and disease tissues and is compatible with droplet-based single-nucleus RNA-Seq technologySlyper et al. This method is part of a toolbox for processing frozen tissue samples forsingle-nucleus RNA-Seq, including the CST (this protocol), TST and NST protocols (all available inprotocols.io). We recommend users to test all three protocols on their tissue type of interest and perform side-by-side comparison of the data generated. A description of the complete toolbox andguidance for testing and selecting methods from the toolbox for processing other tumors can be found in Slyper et al. For the Human Tumor Atlas Pilot Project (HTAPP), the CST-nuclei isolation method was used to profile pediatric glioma frozen samples. It was also tested on metastatic breast cancer, ovarian cancer, pediatric sarcoma, and pediatric neuroblastoma frozen samples. For these cancer types, however, TST was the protocol of choice.
