RNA-seq of CD8+ T cells
Total RNAs were extracted from CD8+ P14T cells using TRIzol Reagent (Invitrogen, cat. NO 15596026）following the methods by Chomczynski et al (DOI:10.1006/abio.1987.9999). DNA digestion was carried out after RNA extraction by DNaseI. RNA quality was determined by examining A260/A280 with NanodropTM OneCspectrophotometer (Thermo Fisher Scientific Inc). RNA Integrity was confirmed by 1.5% agarose gel electrophoresis. Qualified RNAs were finally quantified by Qubit3.0 with QubitTM RNA Broad Range Assay kit (Life Technologies, Q10210).
