title: Notch Signaling and Efficacy of PD-1/PD-L1 Blockade in Relapsed Small Cell Lung Cancer  : Sample CL0114_T1
design: Formalin‐fixed, paraffin‐embedded (FFPE) tumor tissue samples were prepared for whole‐exome sequencing (WES) and RNA sequencing (RNA‐Seq). One hundred nanograms of DNA was sheared to approximately 200 base pairs (bp) by sonication (Covaris, Woburn, MA). Exome enrichment was performed using SureSelect Clinical Research Exome Kits according to the manufacturer's instructions (Aglient, Santa Clara, CA).
